Veneers are very thin shells that are attached to the front part of teeth. They are often made of porcelain or composite resin. Porcelain veneers are stronger than composite resin veneers and do not change colour or stain.
How composite resin veneers are done
The dentist puts a mild chemical on the front surface of the tooth to make it a little rough. This helps the composite resin to stick to the enamel of the tooth. The composite resin that matches the colour of your natural teeth is chosen so that the veneer blends in with your teeth. The dentist then puts the composite resin on your tooth in layers. A bright light is used to harden each layer of the composite resin. After the last layer of composite resin is hardened, your dentist shapes and polishes it to form your tooth. The finished tooth looks natural and smooth.
How porcelain veneers are done
With porcelain veneers, your dentist may give you a local anesthetic. Your dentist then removes a thin layer of the enamel from your teeth to make room for the veneers. Then your dentist makes a mold of your teeth. This mold is used to custom-make your porcelain veneers. In the meantime, your dentist may place temporary veneers to replace the portion of the tooth that was removed. These are temporarily cemented until your porcelain veneers are ready. The temporary veneers are very fragile and need to be treated gently during eating and cleaning as they come loose very easily.
On your next visit, your dentist removes the temporary veneers and puts a mild chemical on your teeth to make them a little rough. This helps the porcelain veneers stick to your teeth better. The porcelain veneers are then glued to your teeth one by one, using composite resin cement.
