Abstract
This invention relates to dentistry, and more particularly to cosmetic dentistry, where for aesthetic objectives it is desirable to remove a small amount of the patient's tooth enamel to modify tooth color. A procedure is described using an applicator and compound which provides accelerated treatment time in stripping away a sufficient amount of the outer layer of the tooth enamel to provide the necessary tooth color modification. The applicator has two functional ends. One end has a containment pocket for holding the compound, and a second end for high pressure scouring of the tooth enamel. The compound comprises an enamel softening acid, such as hydrochloric acid, in the concentration range of between 6%-16% in combination with an abrasive particulate material. The abrasive material should have a hardness greater than 6.0 as measured on the Mohs hardness scale for greatest effectiveness.
