A veneer is a thin layer of porcelain or composite made to fit over the front surface of a tooth, like a false fingernail fits over a nail. Veneers are used to improve the colour, shape and position of your teeth.
A precise shade of material can be chosen to give the right colour to improve a single discoloured or stained tooth or to lighten front teeth (usually the upper ones) generally.
A veneer can make a chipped tooth look intact again. The material used covers the whole of the front of the tooth with a thicker section replacing the broken part.
Veneers can also be used to close small gaps, when orthodontics (braces) are not suitable. If one tooth is slightly out of position, a veneer can sometimes be fitted to bring it in-line with others.
