A tooth veneer or dental veneer is a thin layer of porcelain made to fit over the front surface of a tooth, very much like a false fingernail fits over a nail. Sometimes a natural colour composite material is used instead of porcelain.

A precise shape and shade of porcelain can be chosen to lighten the upper front teeth or to reshape them. It can make a chipped tooth look intact again – the porcelain covers the whole front of the tooth replacing the broken part.

Veneers can improve the colours, shape and position of teeth, and protect teeth from further damage caused by acids in foods and drinks or from acids in the stomach. Without the protection of a veneer, the teeth can become thin and weak.

Veneers are often used to close small gaps when orthodontics is not suitable. If one tooth is slightly out of position, a veneer can be fitted to bring it into line with the rest of the teeth.
