If you have a large cavity that's too big for a filling, it may be time for a crown. Dental veneers are thin, tooth-colored shells that are attached to the front surface of teeth to improve their appearance. They're often made from porcelain or resin-composite materials and are permanently bonded to your teeth.
Veneers can be used to treat a number of different cosmetic concerns, including chipped, broken, discolored, or smaller-than-average teeth.
Some people may only get one veneer in the case of a broken or chipped tooth, but many get between six to eight veneers in order to create an even, symmetrical smile. The top front eight teeth are the most commonly applied veneers.
