Dental veneers are extremely thin, tailor-made shells that cover the front surface of teeth to improve your appearance by changing their colour, shape, size, or length. Veneers are usually made of porcelain or composite resin.
Porcelain veneers are stronger than composites. A thin layer of the enamel is removed from your teeth to make room for the veneers, which are created from molds of your teeth. While they are being made in the laboratory, temporary veneers may be put in place. Several days later we remove the temporary material and put a mild chemical on your teeth to roughen them a little, helping the porcelain veneers to stick. The porcelain veneers are then bonded to your teeth, using composite resin cement.
They generally last at least 5-10 years and do not stain or change colour. They also better mimic the light-reflecting properties of natural teeth.
With composite resin veneers, the resin is applied on your tooth in layers. When the last layer is hardened, we shape and polish the veneer to form your tooth, colour-matching it to your other teeth. Although there is less removal of enamel, resin veneers generally do not last as long as porcelain (usually not more than 4-5 years) and are not as strong or as colour-stable.
