A
veneer is a thin layer of porcelain made to fit over
the front surface of a tooth, very much like a false
fingernail fits over a nail. Sometimes a natural
colour composite material is used instead of porcelain.
Veneers
can improve the colours, shape and position of teeth.
A
precise shape and shade of porcelain can be chosen to lighten
the upper front teeth or to reshape them.It can make a
chipped tooth look intact again- the porcelain covers the
whole of the front of the tooth replacing the broken part.
Veneers are often used to close small
gaps, when orthodontics is not suitable. If one tooth
is slightly out of position, a veneer can be fitted
to bring it into line with the rest of the teeth.
Veneers can protect teeth
from further damage caused by acid in foods and drinks
or from acids in the
stomach that cause the teeth to wear away. The teeth
become thin and weak and can be protected by veneers.
How
are teeth prepared for a veneer
Some of the outer enamel surface of the tooth will
be removed, to ensure that the veneer can be bonded to
the tooth permanently. The amount of enamel to be removed
is minimal an will be the thickness of the veneers to
be fitted.
The tooth is prepared in two
stages. The first stage will involve removing a small
amount of enamel and taking an impression of the tooth.
The impression is sent to the laboratory where they will
reproduce a veneer to fit the tooth. We will place a
temporary veneer on the tooth to protect it against sensitivity.
A visit to the laboratory is essential to make sure the
colour is matching the adjoining teeth and will look
natural. The second stage will involve placing the veneers
on the required teeth with a bonding material. A veneer
can be placed in 4 days.
How long will a veneer last
Veneers can last for some years but
they can chip or break, just as your own teeth can.
People who grind their teeth or clench put more stress
on the teeth and the veneers and the life span will
be shorter.
What happens after a veneer is fitted?
Some minor adjustments might be needed
to make sure that you bite is correct. We would like
to recall you one week after to make sure you are
happy with the fit and function well with the new
veneer. |
