FIELD OF THE INVENTION [0002] The present invention relates to tooth whitening substances, and more particularly, to tooth whitening substances including a polyox resin. BACKGROUND OF THE INVENTION [0003] A recognized consumer need is a low cost commercial oral care delivery system that is comfortable to wear that can deliver a sufficient amount of an oral care substance for rapid delivery of an active contained in such substance. In addition a delivery system is needed which does not require extensive user placement manipulation to be certain of good contact for optimal delivery. Furthermore, what is needed is a non-bulky active containment means that will permit the wearer to use the system during social discourse without interfering with the wearer's speech or appearance. Also needed is a containment means that will protect oral care substance from erosion from contact with other oral surfaces and, or saliva. [0004] A recognized consumer need is also a low cost commercial oral care substance that is comfortable to wear that can deliver a sufficient amount of an oral care active to a plurality of teeth. Further, there is a continuing need to provide an oral care substance which can adhere to a plurality of teeth as a thin film. SUMMARY OF THE INVENTION [0005] An oral care delivery system comprising a strip of material and an oral care composition is provided. The oral care composition comprises a tooth bleaching agent and fluoride. The oral care delivery system is applied to the surfaces of a plurality of teeth and wherein the overall thickness of the oral care delivery system is less than about 1 mm. [0006] An oral care delivery system comprising a strip of material and an oral care composition is provided. The oral care composition comprises hydrogen peroxide, and phosphate. The oral care delivery system is applied to the front, incisal edge and lingual surfaces of a plurality of teeth wherein the overall thickness of the oral care delivery system is less than about 1 mm. [0007] A method of treating a plurality of teeth comprising adhesively attaching an oral care product comprising a flexible polymeric film and an oral care composition to the facial, incisal edge and lingual surfaces of a plurality of teeth is provided. The oral care composition is pre-applied to the polymeric film and comprises a peroxide, carboxypolymethylene, and fluoride, and wherein the oral care composition is applied as a stripe to the polymeric film. [0008] The tooth whitening substance includes a polyox resin and a tooth whitening active. The polyox resin adheres the thin layer to a plurality of teeth for a sufficient time to allow the tooth whitening active to act upon the plurality of teeth.
