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.
