ABSTRACT:
Methods for whitening a person's teeth are disclosed. In a first embodiment, the steps include providing a carrier, such as a transparent tape, where the carrier contains a catalyst thereon, and preparing a mixture which includes an oxygen radical generating agent and a buffer. The mixture is then applied to the carrier and the carrier is applied to a person's teeth. The person's teeth are then exposed to a light source. In another embodiment of the present invention, the mixture may include an oxygen radical generating agent, a catalyst, and a buffer. The mixture is then applied to a carrier which is applied to the person's teeth. The person's teeth are then exposed to a light source. In yet another embodiment, a mixture of an oxygen radical generating agent, a thickening agent, and a buffer is prepared and applied to a carrier. The carrier is then applied to a person's teeth which are then exposed to a light source. This carrier may be covered with a layer of release paper prior to use and packaged in a sterile container. In another embodiment a carrier, similar in structure to the carriers described above, is provided. A mixture of bleaching agents, without a catalyst, is then applied to the carrier by the dentist. The tape is then applied to the patient's teeth which are then exposed to a laser light. In another embodiment a non-woven, porous material is used as a carrier. The carrier is dipped into a teeth whitening mixture and then is applied to a person's teeth.
