Introduction
A veneer is a thin layer of
porcelain made to fit over the front surface of a tooth, like a
false fingernail fits over a nail. Sometimes a natural colour
‘composite’ material is used instead of porcelain.
When would I need a veneer?
Veneers can improve the colour,
shape and position of your 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 are the
advantages of veneers?
Veneers make
teeth look natural and healthy. 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.
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’ (mould). 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 make sure that you
are happy with it.
How long will
veneers 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. |
