Sometimes just one or two teeth become discolored because of tobacco use and beverages like coffee, tea and soda. The same techniques are used for “tooth whitening” as for “teeth whitening” but to a lesser degree. For example, we may first try a regular abrasive cleaning of the tooth. This may be followed by a bleaching process on the stained tooth or teeth. Severely stained teeth may require the use of a special whitening gel activated by a laser. We will carefully lighten the tooth until the color matches that of the other teeth.
