What are veneers?
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. Generally, porcelain veneers take at least 2 dental visits to apply and composite resin veneers can be done in 1 visit. Porcelain veneers generally last longer than composite resin veneers.
How composite resin veneers are done
Much like bonding, your dentist puts a mild chemical on the front surface of the tooth to be veneered 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. Your 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.
