  • Patent number: 7802988
    Abstract: 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.

  • Patent number: 5645428
    Abstract: 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 mixture of peroxide and a first catalyst are prepared and applied to the teeth. The teeth are exposed to laser light from an argon laser which light activates the peroxide and catalyst to accelerate the bleaching process without heat. Next, a mixture of peroxide and a second catalyst are prepared and applied to the teeth. The teeth are briefly exposed to laser light from a carbon dioxide laser which heat activates the peroxide and catalyst to accelerate the bleaching process.

  • Patent number: 5009885
    Abstract: A method by which a mucoprotectant gelatin which forms a protective coating on the mucous membranes of the mouth is provided for use with active ingredients for treating the teeth. The active ingredient may be an aqueous hydrogen peroxide solution or fluoride. When hydrogen peroxide is used as a bleaching agent the mucoprotectant prevents the caustic bleaching agent from damaging the gums. The bleaching agent and the mucoprotectant are stored in separate containers and are custom mixed by a supervising dentist and given to the patient in a dispenser so that the resulting slurry may be used in a personalized vacuformed mouthpiece. The treatment may last from several minutes to several hours.
