DictionarySeeteethstained teeth
stained teethDeep or superficial discoloration of teeth. A number of conditions cause this (e.g., exposure of the fetus to tetracycline the mother took during pregnancy or mottling caused by exposure to high levels of fluoride in drinking water). The stains may be covered by applying a resin or porcelain laminate veneer over the stain (bonding). The same technique may be used to rebuild or repair chipped or cracked teeth. |
