A veneer is a porcelain facing which covers the front surface of the tooth; they are mainly used to improve the appearance of the particular tooth, which is often an incisor tooth.

Veneers are used when a tooth has several fillings which do not match or have become stained; they can also be used to disguise gaps between teeth. Veneers are simply cemented onto the tooth. They are less destructive than having a crown as less tooth tissue needs to be prepared.
