Q
What is a veneer?
A 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.
Q What are the advantages of veneers?
A 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.
Q When would I need a veneer?
A 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.
Q What about alternatives?
A 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.
Q How long will a veneer last?
A 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.
Q How are teeth prepared for a
veneer?
A 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.
Q How long will it take?
A 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.
Q Will I need a temporary veneer
between visits?
A 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.
Q What happens after the veneer
is fitted?
A 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. |
