Wearing away of a tooth. It may be caused by incorrect tooth brushing (The point where the tooth meets the gum is particularly vulnerable as the root may have become exposed). It can be made worse by the use of abrasive toothpaste (e.g. smokers). Any damage near the gum may be extremely sensitive and need treatment from a dentist. Sensodyne may be an effective remedy.
An accumulation of pus which is formed at the root of a tooth. The tooth will be very tender and there will be an intense throbbing pain. An abscess in the area where the tooth meets the gum is known as a periodontal abscess. Dental treatment will be needed to effect a cure, but some measures can be taken to ease the pain: Take 2 Solpadine tablets and rinse your mouth with hot water into which you have dissolved a teaspoonful of salt. This will help soothe the pain and assist the healing process.
Accidents that involve injury to the teeth affect all age’s groups. However, children are more vulnerable (just over one third of all five year olds will have suffered an injury to their first [primary] teeth.) By 12 years of age, 20-30% of children will have suffered injuries to their teeth. Immediate action in the event of some injuries, such as a knocked out tooth, gives a much better chance of a good recovery Injuries to the teeth can include the fracture of a portion of the crown, of the tooth, or the root. The fracture can go through enamel only; through into the sensitive yellow tissue under the enamel [dentine] or into the pulp (nerve and blood vessels) in the middle of the tooth.
Injuries can also affect the tissues that hold the tooth in place (periodontal ligament), or the tooth can be loosened or knocked out of its socket completely Accreditation
The dental industry is undergoing dramatic change. Independent practices are facing
new competition with the entry into the market place of a number of big companies
such as Boots and DenCare. In response, some independent dental practices are
seeking to highlight their particular skills by adopting recognised quality management
systems such as Investors In People, The Charter Mark, The BDA Good Practice
Award, and the ISO 9000 Standard. This is accreditation. As they provide a
mechanism that proves that proper practice management controls are in place.
A substance produced by the Adrenal Glands, which prepares the body for fight or
flight. It increases blood pressure, the heart rate, and nervous activity. Local
anaesthetics contain adrenaline in very small quantities. Some patients are sensitive to
adrenaline and it can induce a very rapid heart rate and palpitations. Dentists should
be informed of any allergies/sensitivities.
Toothache experienced during high-altitude flying. It is caused by the expansion of gas within the pulp chamber of a tooth due to the reduction in atmospheric pressure. It is usually the sign of a dead or infected tooth that is in need of treatment.
The techniques used to improve the position, colour shape and symmetry of the teeth
and jaws. Aesthetic dentistry techniques are used to improve the appearance, as well
as the function, of the teeth and mouth. Orthodontic treatment is included under this
A mixture of finely powdered silver, a small quantity of copper, and mercury which
forms a plastic material used to fill a tooth. Once tightly packed into the prepared
tooth, the material is then carved into the required shape. It will set within a matter of
hours to form an extremely durable, and long lasting filling. This is often referred to
as a "silver amalgam filling".
The sudden and dramatic collapse of the circulatory system as the result of an acute allergic response (e.g. from a bee or wasp sting). There may be a rapid drop in blood pressure that causes a loss of consciousness in which case emergency treatment is required. This consists of the administration of antihistamines or cortisones. The condition can prove fatal.
A condition in which the tooth attachment disappears and the root
becomes bonded to the jawbone making extraction of the tooth difficult orimpossible. The condition is more likely to be associated with a dead or
root treated tooth.
A rare genetic condition that causes the teeth to fail to develop. It can be either complete (a total absence of teeth) or partial anodontia [only one or two teeth may be missing] The most common site is the upper lateral incisors. The condition is hereditary.
Drugs that can help clear up infections caused by bacteria, but not by viruses, worms
or fungi. Distinguishing illnesses which result from bacterial infections (as opposed to
viral, worm or fungal infections) is the key to using them successfully.
The tip (apical) area of the root of a tooth. If this part of the tooth has to be removed
the surgical operation is called an apicectomy or root re-section. The apex is a very
important part of the tooth. The blood and nerve supply, which keep the tooth alive,
run through a small opening in it into the root canal.
A fever causing illness when bacteria are present in the blood stream. Of particular
concern to patients who may have a heart condition or have suffered from rheumatic
fever. Patients with a history of these conditions should be given antibiotics to prevent
or control bacteraemia during dental procedures.
An unpleasant smell expelled by the mouth. It often arises as a result of poor oral
To eliminate bad breath a good oral healthcare routine is essential - regular tooth
brushing and flossing - and visits to your dentist for regular check-ups.
Baking Soda is used in a variety of household tasks particularly in cooking. It has a slightly alkaline reaction and is able to bring a near neutral balance pH to either acid or alkali solutions. It can deodorise many foul smelling compounds and will reduce mouth odour created by garlic. Used in toothpaste it has a cleaning effect and it leaves the mouth and gums feeling fresh and healthy. Mixed with a little table salt and brushed gently into the gums it will help to heal damaged tissues and dissolved in a little cold water will give a refreshing mouth rinse.
Retaining devices made of stainless steel which are bonded to teeth and which are
then used to attach springs and hooks in order to move the teeth into line.
Elastic bands used to move teeth for orthodontic purposes, expanding retaining bands
that are used to retain filling materials.
A condition caused by the inflammation and swelling of the facial nerve that paralyses the facial muscles. It usually only affects one side of the face and it is very noticeable if the patient tries to smile or blink their eyelids. The onset of the paralysis is frequently associated with the patient having been exposed to a cold draught on the side of the face (for example driving with the car window open). Treatment is sometimes assisted with the use of anti-inflammatory agents such as cortisones. Many cases will return to normal after 4 to 6 weeks but it is important to seek medical advice in the beginning.
The removal of a small piece of soft or hard tissue for microscopic examination. The
operation is usually carried out under a local anaesthetic. The tissue is sent to a
laboratory for cellular diagnosis. A specialist (histologist or pathologist) will study the
cells under magnification and diagnose any abnormalities.
Bonding is a term used to describe a number of procedures that involve applying composite resins to the tooth. Composite resins are plastic materials made of micro particles of glass and resin. Bonding can be used to treat fractured, cracked or chipped teeth; badly stained teeth; or teeth that are loose. It is also used extensively in orthodontic treatment to attach the bands and springs that are used to change the positions of the teeth.
Appliances that are fitted to the teeth to improve their position and alignment. Braces
are either fixed to the teeth by brackets that are bonded to the enamel surfaces or they
are removable. Removable braces are wires and springs attached to a plastic resin
base. Braces are also known as orthodontic appliances.
A device used to span a gap left by a lost tooth [or teeth]. There are two types of bridge - conventional bridge and adhesive bridge. Conventional bridge A false tooth is attached to a crown on one or both sides of a gap between teeth.
Tooth grinding. This is often caused by stress and usually happens unconsciously at
night. It is damaging to teeth so a flexible mouth guard should be worn at night to
reduce its effects.
The tooth surface which lies in contact with the cheeks (the buccinator muscle). It
usually only refers to the back teeth touching the cheeks.
Hardened plaque. Calcium salts produced by saliva harden any plaque which is left on the surface of teeth. These deposits are particularly liable to build on the tooth surfaces nearest to the salivary ducts beneath the tongue and in the cheeks close to the upper first molars. The presence of calculus indicates alkaline saliva and a low risk of caries or decay. Smoking tends to encourage calculus formation. The build up of calculus must be controlled by scaling of the teeth otherwise gingivitis and the breakdown of the tooth attachment can occur.
Cancer of the mouth and pharynx is the fifth most common form of cancer in men and the seventh most common in women. Most people are not aware of its existence Cancer of the mouth is responsible for nearly 3% of all cancer deaths. There is a 50% survival rate in those cases diagnosed at an early stage. Factors which are commonly associated with cancer of the mouth are smoking and alcohol. Regular examination of the mouth will reduce the likelihood of an early lesion being unnoticed. Any ulcer of the mouth which is present for more than a few days should immediately be seen by a dental surgeon.
Used as temporary fillings in cases of emergency, when many fillings have to be done in a short period of time, or when further treatment to a tooth may be required. They are made of zinc oxide and eugenol or similar materials and may last for a few weeks to many months. There is also a stronger type used to fix crowns and bridges permanently.
A bony substance covering the root of a tooth which is part of the tooth attachment to
the jaw bone. This area can become exposed when the gums recede and, due to the
presence of nerve fibres, can lead to discomfort and sensitivity.
Teeth can chip due to trauma, but they can also fracture through underlying tooth
decay (cavities). Teeth that are brittle due to root canal treatment, congenital
abnormality or bruxism (tooth grinding) may chip more easily.
A tooth may have damage to the hard tissue ‘a chip or fracture of the crown or crown
and root’ or it may have damage to the supporting soft tissues and blood vessels. The
fracture can go through enamel only, through into dentine (sensitive yellower tissue
under the enamel) or into the pulp (nerve and blood vessels). It is important to have
the teeth checked to ensure that injures are treated appropriately and promptly.
A chronic condition is a long-term disease, illness or injury (as opposed to an ‘acute’condition which is short-term.). Chronic conditions are extremely difficult to cure permanently and tend to recur. Long term monitoring of these conditions is essential. The most common chronic dental conditions are associated with gum disease. To avoid this regular dental visits are essential.
Cold sores are small eruptions usually affecting the lips at the point where the lip joins
the skin of the face. They tend to recur in the same place. They begin as a tingling
sensation, and then a small blister (vesicle) forms, which then crusts over to leave a
small scab that eventually heals.
They are caused by a virus called herpes simplex virus (HSV). It is similar to the virus
that causes chickenpox, as are the blisters that result.
Composites are tooth coloured resin filling materials. They are used as an alternative when an amalgam filling is not cosmetically acceptable. The quality of the finished result will vary depending on the experience and craftsmanship of the practitioner.
The part of a natural tooth which is exposed in the mouth is called the crown and is
covered in enamel. The term is also used to refer to an artificial covering that is made
from metal [e.g. gold], or porcelain, to restore or conserve a damaged tooth.
A tissue sac which becomes filled with fluid. If left untreated it will gradually enlarge
and cause the surrounding bone to resorb. Cysts are most frequently found at the
pointed bottom [apex] of a dead or infected tooth. They are rarely associated with any
symptoms in their early stages but can become infected and painful.
Deciduous Teeth [primary, temporary, milk or baby teeth]
So-called because like the leaves on some trees they are eventually shed or exfoliated.
The deciduous teeth start shedding from the age of 5 years or so [slightly earlier in
girls] with the loss of the lower central incisors. The replacement process finishes
when the last deciduous molar is lost by about 12-13 years of age.
The calcified part of a tooth beneath the enamel which surrounds the pulp chamber
and root canals. It contains microscopic channels [tubules] that contain nerve fibres
that connect to the dental pulp. Dentine is the "living" part of the tooth. Dentine can
regenerate when it has been damaged but this is a very slow process.
The industry involved in the care and treatment of the tooth and its associated areas. It is currently undergoing considerable change. In the past, the NHS dominated the service. It suffered from underfunding and centralised controls. Now, the private [non- NHS] sector is growing rapidly, bringing with it new investment, better services and new technology.
A gap or space between two teeth. Most commonly used to describe a gap between the upper two central incisors when the lip attachment (fraenum) causes a separation of these teeth. The diastema can sometimes be as much as 2-3mm and surgery, together with orthodontic treatment, may be needed to correct it.
The letters are used as a dental index to indicate the dental health of a population (e.g.
D=decayed, M=missing and F=filled).
So for example a DMF index of 4.6 in 16 year olds will mean an average of 4.6 teeth
are either decayed, missing or filled per child.
A temporary filling material used to help relieve toothache. The material often contains Eugenol and Zinc Oxide which is inserted into the tooth as a paste and then gradually hardens over 24 hours or so. Eugenol(found in oil of cloves)has been used for generations to treat dental pain.
‘Dry Mouth’ [Xerostomia] is associated with a reduced output or absence of saliva, producing dryness of the mouth. Its effects can be reduced by using the following techniques: • Brush your teeth after every meal and before you go to bed • Drink plenty of water • Chew a sugar-free gum • Avoid sugary food and drink • Avoid using a mouthwash with an alcohol base
A dry socket is the most common complication following a dental extraction. The
socket becomes infected and will begin to become very painful. A bad taste and foul
smell will be present. It is important to return to your dentist for treatment without
Enamel is the hard glossy natural protective coating that covers the crown of a tooth. There are no living cells present and it is therefore insensitive. It is translucent so the colour of the tooth is dependent on the colour of the underlying dentine. With the exception of diamond, it is the hardest naturally occurring substance known to man.
A specialist field of dentistry concentrating on the preservation of diseased or
damaged teeth. Endodontic treatment or root canal therapy (RCT) carried out by
specialists can save teeth which, until recently, would have been extracted.
An instrument used to transfer facial recordings and measurements to an articulator to give correct jaw relationships. It is important to have these recordings made in complex restorative work to ensure that the natural articulation is preserved.
Materials placed in the teeth to replace lost tooth substance. Various materials are used
Amalgam: [see amalgam] Composite: [see composite] Glass Ionomer: [see glass
Ionomer] Cements: [see dental cements]
A permanent hole or opening in tissue through which fluid can drain. The most
common type of fistula can occur during the extraction of an upper molar where the
roots are very close to the sinuses. If the lining of the sinus is breached an opening
(fistula) connecting the mouth to the nasal airways can occur. If this is not treated, the
tissues can heal and leave an opening through which food can leak into the nasal area.
A piece of fleshy mucous tissue that is associated with the lip attachment. An
exaggerated fraenum in the centre of the inside upper lip may cause an unsightly
central gap between the upper incisors - see diastema.
An electrical charge that is created when two dissimilar metals come into contact. The
sensation is most frequently experienced when a new amalgam filling has been placed
in a tooth which comes into contact with a gold restoration. Silver paper or a fork
coming into contact with an amalgam filling may cause an electric "shock" or a
metallic taste. In severe cases, the filling may have to be replaced with a "white" nonmetallic
By use of injection or gas to render a patient unconscious in order to carry out a
The NHS and the General Dental Council actively discourage GA in general dental
practice in favour of hospital facilities.
A tooth germ or follicle can become split or divided during its development which can
give rise to the formation of an "identical twin" or supplemental tooth. This may be
related to a genetic or inherited defect.
Tooth coloured filling material made from glass. It can be used in small shallow cavities but it generally has poor strength. It is very useful in children’s teeth and can leach fluoride, which helps prevent further decay. It is sometimes used with dental composite to help the sealing of the tooth. Like composite it is very sensitive to moisture before it has set.
A condition in which the enamel fails to develop properly. This can occur if the patient suffers a serious illness whilst the tooth germ is developing leaving a defective line on the surface of the tooth.
The insertion of titanium posts into the jaw bone onto which crowns are fixed. The
discovery that Titanium could be implanted into bone was made in Sweden by
Professor Branemark in the 1970s. Given the right clinical conditions he found that
cylinders of titanium could be implanted into human bone and after a few months they
A negative or mould of a tooth or teeth that is taken in order to make an accurate replica or die in a durable material on which to make prosthesis (denture, crown, bridge etc.). The impression materials most commonly used are made from alginate.
A procedure to restore teeth. When cavities become too large and an ordinary filling is
not strong enough to cope with the required biting forces the dentist will need to have
stronger fillings made in the laboratory.
Inlay - fits inside the tooth
Onlay - fits over the tooth
They are made of various substances e.g. gold, porcelain, etc and last for about 10 to
15 years. They are cemented or bonded to the tooth.
The covering of dental costs by regular payments. Comprehensive Plans - Premiums are calculated based on the patients dental condition so, those with poor teeth can expect to pay a higher premium. Many plans will require dental fitness before acceptance and contain provisions for additional charges such as laboratory fees where crowns, bridges, dentures etc. are concerned. Expensive items such as implants are excluded. Insurance - These low cost schemes provide a generous cash benefit for the restoration of teeth in the event of damage from an accident. Benefit for the treatment of oral cancer is usually also included. Advanced materials and dental technology in the form of titanium implants can bring about the most incredible restorative transformation. This treatment is expensive and not available under the NHS. So Insurance cover is an attractive purchase. Dental Cash Plans - Similar to Hospital Cash Plans where a number of dental conditions attract cash benefits.
UKAS Accredited Practices (ISO 9000) An audit mechanism that confirms that a dental practice has met all the practice management criteria that are outlined in the ISO9000 Series quality management systems. Dental practices that display the Royal Crown have demonstrated their commitment to best practice and are justifiably proud of their achievement.
The area or junction of bones at which movement can take place. The ends of the bones are covered in cartilage and bathed in a fluid that lubricates the surfaces. The temporo mandibular joint or "jaw joint" is where the mandible joins the base of the skull just in front of the ear.
The surface nearest or adjoining the lips (the labialis muscles). Hence the labial surface of a tooth refers to the front of the upper and lower incisor teeth. A dentist will use the term when describing [charting] a mouth to identify the position of a cavity or a filling.
A condition that may affect the lining of the mouth and tongue. It is an inflammatory
condition that causes soreness, sensitivity and discomfort. The condition has a variety
of appearances. It is commonly seen as a network of fine white lines on the inside of
the cheeks, often on a reddish background. Less commonly it can appear as white
patches of different sizes and shapes on the tongue or roof of the mouth. Occasionally
the gums can be affected, both with white patches and, sometimes, shiny red sorelooking
Thread usually made of silk or cotton used to tie off blood vessels or stitch tissues together. It is removed when healing is well advanced. In some instances, a dissolvable material [e.g. catgut] is used to bring the deeper tissues together before the surface tissues are repaired. These deep stitches [sutures] are then left undisturbed.
A local anaesthetic commonly used in dentistry and often combined with 2%
adrenaline to prolong the effect by reducing the blood flow. A dental anaesthetic can
last for as long as 3 hours and patients should take great care not to drink very hot
fluids or chew on the affected side until the normal sensation has returned. It is very
easy to bite the anaesthetised area and cause serious soft tissue damage and ulceration.
Tooth at the back of the mouth that is used for crushing and grinding. There are eight
deciduous molars and twelve permanent molars although the third molars (wisdom
teeth) often fail to erupt because of lack of space in the jaw (impacted).
A device worn over the front teeth to protect them from damage. Usually worn during
sporting activities. They are made from a flexible material designed to cover the upper
teeth and protect against the effects of a blow to the face. A properly designed mouth
guard will also minimise the damage to the soft tissues.
A fluid that seeks to reduce or eliminate damaging bacterial activity and help to interfere with plaque formation. There are different types including fluoride rinse to protect against tooth decay, general purpose daily rinse to supplement the tooth brushing routine and reduce bacterial activity, and specialist rinses for short term use to help control a chronic gum condition.
A painful area affecting the soft parts of the inside of the mouth: the cheeks, lips and
Seven million people in the UK get mouth ulcers each year - 16% of the whole
population. Despite being small, ulcers can be very painful and make eating, drinking,
talking and even kissing very painful.
Pain arising from a nerve trunk or pathway. Very severe facial pain can be caused by trigeminal neuralgia which affects the face. It can be severely debilitating, sometimes requiring surgery to cut the nerve supply.
The sweet smelling gas used during the early days of general anaesthesia in dentistry -
known as laughing gas. It is rapidly absorbed into the blood stream and has analgesic
effects. Nitrous oxide is still used in obstetrics mixed with oxygen to reduce the
discomfort of child birth.
The patients input of food and drink. The quality and type has a significant effect on general and dental health. Sugar is a major contributor to dental decay. A key finding is that tooth decay depends on how often - rather than how much - sugar is eaten. The dental profession recommends restricting sugar intake to no more than three or four times a day.
A specialised cell that is responsible for laying down the calcified substance called dentine that surrounds and protects the pulp tissues. Odontoblasts remain active throughout life and are continually laying down new dentine during the ageing process. It gradually seals up the minute channels previously occupied by nerve fibres and reduces tooth sensitivity.
The dental process that straightens teeth or brings teeth into a regular arrangement
[the correction of malocclusion].
In recent years orthodontic technology has improved dramatically and with the use of
fixed appliances (train tracks) teeth can be moved significant distances into perfect
A form of dental shorthand used to describe individual teeth.
The mouth is divided into four parts called quadrants, upper left quadrant, upper right
quadrant, lower left quadrant, and the lower right quadrant. Each tooth in the quadrant
is then given a name and a number (e.g. the two upper and two lower teeth at the
centre of your mouth are called centrals or 1's). The numbers of these teeth, added to
the quadrant in which they are placed, give a precise location e.g. the central on the
upper right side of your mouth is called an upper right central or upper right 1.
The disease of the tissues around the tooth.
Plaque left at the neck of the tooth may cause an inflammation below the top of the
gum. This affects the supporting structures of the tooth - the elastic (ligament) fibres
that attach the tooth to the bone, and the bone itself. The inflammation will eventually
destroy this attachment resulting in ‘pockets’ along the root of the tooth and finally a
loose [mobile] tooth.
The tooth supporting structure that attaches the root of the tooth to the jawbone. This is a very complex structure which allows for microscopic movements of the teeth to ensure that mechanical stresses are evenly distributed.
The area around the neck of the tooth that forms as a result of the gum tissue becoming detached. Very deep pockets can develop which harbour bacteria and threaten the whole tooth attachment (periodontium) resulting in loosening and tooth loss.
Teeth have to withstand very heavy demands during pregnancy. In the absence of excellent oral hygiene measures this can have a devastating effect on the teeth. A good balanced diet taken at regular mealtimes with plenty of calcium, vitamins and minerals are essential during pregnancy for both mother and developing child. It is not uncommon for the gums to become inflamed and start to bleed during the last six months of pregnancy. This is quite natural and is a direct result of the hormonal changes that take place within the body. A mouth rinse such as CORSODYL is a useful product to help reduce this inflammation. It is important to see a dentist at the beginning of the pregnancy, about two months prior to delivery and again when the baby is about three months old.
Fixed prostheses can be used to replace the missing teeth and take the form of crowns or bridges. Removable prostheses are worn by those who have lost all of their teeth (complete dentures) some of their teeth (partial dentures) or Prosthodontics
The term applied to those who specialise in the provision of fixed or removable prosthetic (prosthodontic) appliances to the teeth. Worn by children to straighten their teeth (orthodontic appliances).
The soft inner structure of a tooth, consisting of nerve and blood vessels. It is
contained in the pulp chamber which is the very inner part of your tooth containing
nerve cells and blood vessels [also known as the pulp canal].
The General Dental Council maintains a Register of all those who can legally practice dentistry in the UK. To be licensed to practice dentistry requires a qualification from a recognised body. Examples include the Royal College of Surgeons (a licence in dental surgery - LDS) or a University Degree (bachelor of dental surgery - BDS). Higher or post graduate qualifications can be taken in order to be recognised as a specialist.
A period of isolation to prevent the spread of a contagious infection. Special isolation
units are sometimes necessary to prevent epidemics of serious diseases infecting large
numbers of the population.
Sensitive films that give a permanent record of relative tissue densities when they are exposed to x-ray radiation. Highly calcified dense areas of bone or tooth substance will prevent the transmission of radiation and so will show as opaque or white areas on the film. The dark areas of film indicate areas of lower tissue density. They are used to identify any abnormalities in the teeth and gums that may need treatment.
A sensation of pain that occurs in an area which is different from the area causing the
problem. The very complex nature of the facial nerves sometimes makes it difficult
for a patient to accurately signify where the source of the pain originate e.g. at the
start of a dental abscess it is possible to perceive that the pain may even be coming
from the opposite jaw.
A mixture of nitrous oxide ["laughing gas"] and air is still used frequently as a very safe method of reducing pain. It is used in dentistry and midwifery in conjunction with local anaesthesia. The patient remains in a cooperative state of consciousness and the effects wear off very quickly.
The bone structure remaining following the loss or extraction of teeth. The lower (mandibular) ridge tends to suffer more from residual bone loss than the upper and this makes it more difficult to stabilise a lower denture.
The process of returning the tooth and its surroundings to its previous condition after
damage or loss has occurred.
Dental technology and materials have advanced rapidly in recent years. The more
advanced technical procedures require special skills and knowledge.
The chamber in the middle of a tooth that contains the nerve [pulp]. Root canal treatment is carried out when the pulp (or nerve) inside the tooth is damaged or becomes infected. If infected pulp is not treated, it may become an abscess.
The fluid which contains enzymes that is formed by glands in the mouth. The saliva
helps to lubricate the mouth whilst the enzymes are an important part of digestion.
Lack of saliva [dry mouth or xerostomia] is an extremely distressing condition which
is experienced by an increasingly large proportion of the population.
Saliva is responsible for lubricating the teeth and mouth tissues which makes
chewing, eating, swallowing and speaking possible. It helps to cleanse the mouth,
neutralise acid production, begin the digestion of carbohydrates, repair the early
damage caused by tooth decay, and it has the ability to protect against infection.
A healthy adult produces about 500mls per day and the flow normally increases at
meal times in response to chewing. Some sour fruits such as lemons will promote an
exaggerated flow of saliva.
A plastic coating which, when applied to the grooves and pits on the biting surfaces of children’s teeth, can protect them from decay. If a small amount of decay has already occurred in part of a groove the decay must be removed. Provided the resulting cavity is small, a sealant restoration can still be used to fill the hole and seal the remaining grooves.
The use of safe and effective drugs to help nervous and apprehensive patients to relax. It ensures that the patient is fully conscious, but at the same time relaxed and co- operative. The dentistry is carried out under local anaesthesia to eliminate any painful experiences and patients often forget about their dental treatment and find the events difficult to recall. Hypnotherapy and even acupuncture have also been used to reduce dental anxiety.
An opening into a tract of tissue which is linked to the oral cavity. Usually associated with an infected tooth root. Also a term used in association with the major air cavities in the maxilla which can become infected and give rise to sinusitis.
An infection of the cavities in the maxilla situated behind the cheek-bone. The
symptoms can frequently give rise to toothache in the upper premolar and molar
regions. Fluid can build up and the pain can be made worse by sudden movement of
Antibiotics may be required. Inhalation with eucalyptus and menthol can help to
alleviate the discomfort and clear the sinuses.
Making a variety of noises when exhaling during sleep. About 40% of the population snore. At best it is a nuisance but at worst it can give rise to serious medical problems. Invariably snoring occurs whilst sleeping on one's back and it is caused by a temporary blockage of the airways by the soft tissues at the back of the throat. More modern methods involve the fitting of appliances in the mouth to prevent the soft tissues obstructing the airway. In exceptional circumstances surgery may be required. There are a number of dental surgeons who specialise in treating snorers.
Manufactured fluids drunk to relieve thirst or by habit. Commonly containing sugar
and/or carbon dioxide
Fizzy drinks (whether diet or regular), artificial fruit squashes, cocoa, and milk shakes
all cause harm to teeth. The sugar in them causes decay whilst the acid in both normal
and diet drinks dissolves the enamel on the teeth. Comfort feeders and bottles
containing sugary drinks, which are given to young children for prolonged periods of
time, cause severe dental problems, because they bathe the teeth in sugar that quickly
converts to acids.
Dentists who offer services in addition to those connected with general dental practice.
Many practices offer a range of specialised services that may not be covered by General Dental Council specialists (see A-Z specialist). A comprehensive list of dental services includes:- Anxiety clinic Cosmetic dentistry Crown and bridgework Dental implants Denture services Endodontics General dentistry Holistic Home visits Hygienist Minor oral surgery Occlusion Oral medicine Oral Surgery Orthodontics Out of hours emergency cover Paedodontics Periodontology(gum care) Preventative dentistry Prosthodontics Restorative dentistry Second opinions Sedation for anxious patients Specialist referrals Surgical dentistry
The General Dental Council maintains a Register of dental surgeons who are qualified
to practice dentistry in the UK. In addition it has lists of specialists who have obtained
certification in particular areas of dentistry which recognises their higher level of
knowledge, experience and qualification.
These specialist areas are:-
Dental Public Health
Dental and Maxillofacial Radiology
Inflammation of the tissues of the mouth. It is particularly common in denture wearers
where food debris and bacteria can quickly set up an inflammatory condition.
Denture-induced stomatitis is a condition caused by Candida, a fungus infection. It is
manifested as redness in the gum covered by a denture, often without soreness.
Persistent cracking or soreness at the corners of the mouth (angular chelitis) may also
be a sign of oral Candida infection.
Extra or additional to the normal. A supernumerary tooth does not resemble the morphology of another in the dental arch and will have developed from an aberrant tooth germ. An additional tooth which resembles the morphology of another is called a supplemental tooth.
A plan to care for teeth and gums through good oral hygiene to allow them to last a ‘lifetime’ Every human is born with a genetic programme which will develop for us two perfect sets of teeth - a deciduous set and a permanent set. Nature has given us a second chance to learn from our mistakes if we fail to keep the first temporary set in perfect condition. By the age of six years we have to have a carefully regulated diet and an effective cleaning programme which will be part of our daily routine. All teeth erupt free of tooth decay and a life-time preservation programme must be put into practice. It is important that life-time habits are developed in the young. Cleaning must be fun and it is the very last thing that has to be done before bed time. Nothing must be eaten or drunk afterwards. If a child has to have a drink by the bed at night then this should only be water. Remember: neglect = tooth decay = pain and expense!
The development and eruption of the first set of teeth in the young.The eruption of the milk teeth is usually accompanied by excessive salivation and a
redness of the cheeks. This is particularly noticeable when the molar teeth appear.
Babies will tend to push things into their mouths to gnaw upon in an attempt to relieve
the soreness. It is rare that the front teeth give much of a problem but the first molar
teeth which appear at about twelve months can give a problem. Eating hard rusks can
help the eruption process.
The second deciduous molars will finally complete the temporary set of teeth at about
the second birthday. These larger teeth frequently give rise to listlessness, sometimes
loss of sleep and can be accompanied by a fever. These symptoms can last for a week
or so with the lower teeth erupting first. These symptoms may reoccur some weeks
later as the upper teeth follow. Disprol or Calpol, and the local application of Anbesol
will often help relieve the symptoms of teething.
The complex hinge joint which connects the mandible with the base of the skull just in front of the ear. Temporo-mandibular joint disorders (known as TMJ disorders or TMD) are the most common condition affecting the jaw joint. TMD is also known as facial arthromyalgia, and literally means face, joint and muscle pain.
An infectious disease spread by the tetanus bacillus which causes severe muscular
spasm and lockjaw. Can be contracted through a cut or wound exposed to dirt or soil.
Can be effectively protected against by vaccination
Babies can be born sucking a thumb or a finger! X-rays sometimes show the
developing child sucking a thumb whilst still in the womb. It is quite normal for
infants to suck a thumb or a finger and only becomes a problem if the habit is allowed
to become persistent from about 2 years of age. The thumb can become very sore,
which usually acts as a deterrent.
A light metal with unique bone bonding properties that were discovered in the 1960's by Professor Branemark. Carefully designed implants are now used extensively in dentistry to replace natural teeth and to anchor bridges and dentures in place.
The discomfort [pain] caused by changes in the health of teeth. The best advice is to
go and visit a dentist as soon as possible.
The teeth and the tooth attachments may give rise to painful symptoms as a result of
decay, abscess, and periodontal (gum) disease or eruption problems. The pain may
vary from an intermittent or fleeting sensitivity to hot and cold that may indicate the
early onset of decay to the most dreadful acute throbbing pain caused by advanced
decay and a dental abscess. In this latter case it may be impossible even to touch the
teeth together and eating may be difficult.
A thick creamy material used, in combination with a toothbrush to assist in tooth cleaning. There are three main categories of toothpaste
family, children’s and specialist. Both fluoride and non-fluoride tooth pastes are available in adult and children’s formulae.
[also known as tic douloureux]
A rare facial pain that causes a sudden, brief but severe electric shock-like or stabbing pain on one side of the face. It tends to be more common in women than in men and usually affects people aged 50 and over.
Spasm of the jaw muscles which closes the teeth tightly together (lockjaw). It occurs
in tetanus and in people who suffer from epilepsy. It may also arise as a result of a
severe infection affecting the jaw muscles e.g. an impacted wisdom tooth.
A volatile material used in dentistry to provide a protective film or sealant. The solution evaporates to leave a barrier against moisture or irritant substances and can be used under filling material to protect the sensitive dentine underneath.
A substance such as adrenaline used in dentistry to restrict the blood supply by
making the blood vessels contract. This can reduce bleeding of the tissues after
surgery and prolong the effect of the local anaesthetic.
A layer of tooth-coloured material, which is attached to and covers the surface of a
tooth. They are usually made of porcelain or composite resin.
Composite resin veneers can be built up directly on the tooth, while porcelain veneers
are made in the laboratory and are later glued (bonded) on to the tooth.
A very small amount of enamel is removed from the tooth surface. This is usually
completely pain free Subsequently, the veneer will be glued to the tooth.
An extremely painful ulcerative gingivitis which can be very destructive. It is
indicative that a patient is very run down and debilitated. The condition used to be
referred to as "trench mouth" as it occurred in soldiers in the First World War who
were exhausted from lack of nourishing food and sleep.
Blood anticoagulant used for patients who have suffered a thrombosis. Patients on
Warfarin must tell the dentist before any treatment is carried out. Special precautions
are needed for tooth extractions. Surgical treatment may need to be carried out in
A material used very extensively in dentistry, especially in prosthodontics. There are so many dental applications that a variety of waxes are made each with specialised properties. Different melting points and strengths are required for various tasks e.g. making replica dentures, or crown forms. The ‘lost wax’ process is the foundation of dental casting techniques.
A process that will result in a change in the appearance of a tooth. The treatment
required will depend on the underlying cause.
Tooth discoloration can be a result of either external factors (surface stain) or internal
factors (internal stain). As a general rule our teeth become darker as we become older
- it is a normal ageing process.
Large teeth at the back of the mouth (third molars or 8’s). They are usually the last to appear, normally in the late teens and early twenties. Wisdom teeth can cause problems because they erupt at the back of the mouth after all the other permanent teeth have erupted and there is very little space left. Wisdom teeth have a habit of slowly breaking through the gum tissues at the back of the jaws. These tissues can then become infected and swollen. It is often the lower wisdom teeth that become the most troublesome. There can be serious facial swelling and a raised body temperature and fever. In these circumstances professional advice should be sought immediately. Other wisdom teeth may never come through but remain buried and impacted at an angle in the jaw.
The reduced output of saliva, producing dryness of the mouth. If you suffer from Xerostomia you can treat it by using the following techniques: Brush your teeth after every meal and before you go to bed Drink plenty of water Chew a sugar-free gum Avoid sugary food and drink Avoid using a mouthwash with an alcoholic base
A reflex action in which air is drawn into the lungs through distended airways and an
open mouth. Usually a sign of tiredness and shallow breathing when the carbon
dioxide levels build up and oxygen levels are depleted.
A white amorphous powder used extensively in dentistry as a component of filling
and impression materials. When mixed with eugenol and used as a temporary filling it
can bring relief for toothache and sooth inflamed tissues.
