Definitions for "Veneers"
a covering applied to the tooth made from porcelain to improve the tooth's appearance
If a stain is very deep within the tooth then porcelain veneers can be considered. Veneers are thin coverings of laboratory-made porcelain which are bonded to the tooth with a special resin. They behave much like a false fingernail which covers the front surface of the tooth. Because they have a glazed surface they feel very smooth and also tend to resist staining. Veneers are often chosen by celebrities to perfect their smile.
These ultra-thin sheets of porcelain or composite resin are created for bonding to the surface of teeth. This procedure is especially useful in repairing or changing the appearance of damaged teeth.
