Abstract: A diamond dust polishing agent for home use and professional use in the care of natural tooth enamel and dental veneers comprised of a quantity of diamond dust coated with a lubricant in conjunction with a paste for carrying the lubricant coated diamond dust, or other semi-precious, non-toxic abrasive dust, said diamond dust being of a size of approximately 500 nanometers or less to a size of approximately 5 nanometers. The size of the dust of both the diamond and the semi-precious stone may vary, depending on the degree of abrasiveness and the lubricant employed. The diamond dust (and semi-precious dust) polishing agent permits the user to maintain the polish and luster of the natural tooth enamel and veneer at home without adversely abrading or damaging the surface thereof.
