An appointment typically takes from one to two hours depending on the number of teeth to be treated. To prepare each tooth, your dentist will remove a thin layer, about the thickness of a fingernail, from the surface of the tooth. This allows room for the veneers to be glued into place later.
A local anaesthetic may be required during this step. An impression is taken of your teeth and sent to a dental ceramist, who manufactures the veneers to fit your teeth.
Cementing of the new veneers occurs at the next appointment and many take a few hours. Your dentist will check on the colour and fit before finally bonding them into place. The teeth are cleaned with a chemical that helps bond the veneer to the tooth.
After a cement is placed between the veneer and your tooth, a light beam activates the cement to bond the veneer firmly. Colour can be altered by using varying shades of cement, so it is important that you discuss any changes you require before the final cementing is done.
Once the veneer is bonded to the teeth, the colour cannot be changed. After the veneer has been bonded, it is trimmed and polished. These are thin, tooth-coloured porcelain (ceramic) shells carefully crafted to bond to and cover the front of unsightly teeth. They are a more conservative treatment than a crown and can often be used as an alternative if the underlying tooth is strong and healthy.
