What are the advantages of veneers?
Veneers make teeth look natural and healthy, and because they are very thin and are held in place by a
special strong bond (rather like super-glue) very little preparation of the tooth is needed.
When would I need a veneer?
Veneers can improve the colour, shape and position of teeth. A precise shade of
porcelain can be chosen to give the right colour to improve a single discoloured or
stained tooth or to lighten front teeth (usually the upper ones) generally. A veneer
can make a chipped tooth look intact again. The porcelain covers the whole of the
front of the tooth with a thicker section replacing the broken part. Veneers can also
be used to close small gaps, when orthodontics (braces) are not suitable. If one
tooth is slightly out of position, a veneer can sometimes be fitted to bring it into line
with the others.
What about alternatives?
A natural-coloured filling material can be used for minor repairs to front teeth. This is
excellent where the tooth supports the filling, but may not work so well for broken
tooth corners. There will always be a join between the tooth and the filling material.
Crowns are used for teeth that need to be strengthened - either because they have broken, have been weakened by a very large filling, or have had root canal treatment.
How long will a veneer last?
Veneers should last for many years, but they can chip or break, just as your own
teeth can. Your dentist will tell you how long each individual veneer should last.
Small chips can be repaired, or a new veneer fitted if necessary.
How are teeth prepared for a veneer?
Some of the shiny outer enamel surface of the tooth may be removed, to make sure
that the veneer can be bonded permanently in place later. The amount of enamel
removed is tiny and will be the same as the thickness of the veneer to be fitted, so
that the tooth stays the same size. A local anaesthetic (injection) may be used to
make sure that there is no discomfort, but often this is not necessary. Once the tooth
has been prepared, the dentist will take an 'impression'. This will be given to the
dental technician, along with any other information needed to make the veneer. The
colour of the surrounding teeth is matched on a shade guide to make sure that the
veneer will look entirely natural.
How long will it take?
A veneer takes at least two visits; the first to prepare the tooth and to match the
shade, and the second to fit it. Before bonding it in place, your dentist will show you
the veneer on your tooth to make sure you are happy with it. Bonding a veneer in
place is done with a special adhesive, which holds it firmly on the tooth.
Will I need a temporary veneer between visits?
Because the preparation of the tooth is so slight you will probably not need a temporary veneer.
The tooth will look very much the same after preparation, but will feel slightly less smooth.
What happens after the veneer is fitted?
Only minor adjustments can be made to the veneer after it is fitted. It is usually best
to wait a little while to get used to it before any changes are made. Your dentist will
probably want to check and polish it a week or so after it is fitted, and to make sure
that you are happy with it.
How much will it cost?
You can have veneers on the NHS. However, many dentists prefer to provide
cosmetic treatment privately. It is important to discuss charges and treatment options
with your dentist before starting treatment.
What is a diastema?
A diastema is a space or 'gap' between teeth - very often your front teeth. This is
very common in children and is part of their normal dental development. About 50%
of children between the ages of 6 and 8 have these. Most of these spaces close
naturally as the mouth and teeth develop. In some cases this gap does not close
naturally and a dentists advice is sought.
What causes a diastema?
There are many factors that can contribute to the development of a diastema. Some
of them include:
- Abnormal bone structure - sometimes the bone between the incisors will have a W-shaped defect
- which can be seen on an x-ray. Such a defect will prevent the teeth from touching.
- Occasionally, there may be some extra tissue between the teeth which prevents them from touching.
- If you bite your lower lip it may aggravate such a problem.
- If your teeth have developed in such a way so as to allow space for the front teeth to drift apart.
- If you have a large tongue it may push the teeth forward.
This is not an extensive list, but covers the main causes.
How will this gap affect me?
A gap between children's teeth often causes concern. It can have an effect on
speech - making 's;' sounds difficult to pronounce, aesthetics, balance and social
behaviour.
What can a dentist do for me?
There are many innovative treatments available - restorative, surgery and orthodontic. Treatment choices vary, and can only be offered after the correct diagnosis has been made. A dentist will need to look closely at the patients medical and dental history, do x rays and clinical examinations and in some cases even do a tooth size evaluation.
Contributing factors may also need to be considered. These include spacing of teeth in the mouth, vertical tooth overlaps, normal growth and development, tooth size and tooth angles.
The best treatment for the particular patient needs to be chosen. It is often more important to treat the cause of the diastema, rather than simply focusing on correcting the gap.
How will my teeth be prepared?
The surface of your tooth will need to be roughened a little so as to give the veneer
more chance of bonding to your enamel. A mould will be made of your tooth and a
porcelain veneer made using this to make a perfect fitting veneer. Veneers can be
trimmed and shaped a little more by your dentist to make them look perfect.
Will it be painful?
You teeth will be sensitive to cold for a while.
How long will the veneer last?
Veneers can last for many years - but, they are not indestructible and can be
chipped or damaged if treated roughly.
