Patent number: 6254388Abstract: A method for whitening teeth which utilizes laser light to activate bleaching agents applied to the teeth. The mouth is first prepared so that the soft tissues of the gums are protected and only the teeth are exposed. The teeth are cleaned to remove any materials which will reduce or nullify the effects of the bleaching agents. A first bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are exposed to laser light from an argon laser which light activates the peroxide to accelerate the bleaching process without heat. If further whitening is desired, a second bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are briefly exposed to laser light from a carbon dioxide laser which heat activates the peroxide to accelerate the bleaching process.Type: GrantFiled: February 2, 1998Date of Patent: July 3, 2001Assignee: BriteSmile, Inc.Inventor: David K.
