If your teeth have brown, yellow or white spots, enamel microabrasion may be the best option for you. In microabrasion, the dentist carefully applies a compound to the teeth to remove superficial stains and discolorations.  If the stains are only on the outer surface of enamel, they can often be easily removed in one visit without the need for anesthetic. This conservative procedure may prevent the need for bonding, porcelain veneers or crowns. Many patients choose to bleach after enamel microabrasion, as this brightens the overall appearance of the teeth.
