Veneers can improve the colour, shape and position of teeth. A precise shade of porcelain 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 porcelain 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 into line with the others.
