Veneers
What is a veneer?
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 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.
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.
