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 necessary.
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 required colour, to improve
a single discoloured or stained tooth or
to lighten front teeth (usually the upper
ones) generally. (see below)
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 (see
example to the left), when orthodontics
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
type of restoration 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 filling material which will stain with
time and look unsightly.
Crowns
are used for teeth which 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.
You will be advised 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 ensure that the
veneer can be bonded permanently in place
later. The amount of enamel to be removed
is minimal and will be the same as the thickness
of the veneer to be fitted, so that the
tooth remains the same size. A local anaesthetic
(injection) may be used to make sure that
there is no discomfort, but in many cases
this is not necessary. Once the tooth has
been prepared, an 'impression' will be taken.
This will be given to the dental technician,
along with any other information needed
for him to make the crown. The colour of
the surrounding teeth is matched on a shade
guide to make sure that the veneer will
look entirely natural. In addition we usually
take a digital photograph of the surrounding
teeth for the technician to see the intricate
shades of the teeth.
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, we 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 minimal,
you will probably not need a temporary veneer.
The tooth will look very much the same after
preparation, but will feel slightly less
smooth. Occasionally the teeth are sensitive.
In these cases we make a special plastic
cover which is similar to a sports mouth
guard, but very thin and translucent, to
reduce the sensitivity and allow you to
drink hot and cold liquids.
