Hydrophobic tooth whitening system and methods of use

Abstract

A tooth whitening system comprising a dental tray having a surface operable to confront a tooth surface, and a tooth whitening composition comprising a whitening agent and a hydrophobic. polymer carrier. The tooth whitening composition is preferably substantially non-water soluble. A tooth whitening kit is also provided using a dental tray and the tooth whitening composition comprising a whitening composition and a hydrophobic polymer carrier.

1 - 27 . (canceled) 
     
     
         28 . A tooth whitening composition having an overall viscosity of greater than 50,000 centipoise and less than 900,000 centipoise, comprising:
 between 0.5 to about 50 weight % of a whitening agent selected from the group consisting of peroxides, chlorites and hypochlorites;   between 1 to about 80 weight of a pressure-sensitive, hydrophobic polymer carrier comprising silicon resin and polydiorganosiloxane;   between 0.1 to 1 weight % of a flavoring agent; and   between 2 to 15 weight % of an adhesion enhancing agent consisting of   polyethylene gelled mineral oil that augments adhesion of said tooth whitening composition to tooth surfaces.   
     
     
         29 . The tooth Whitening, composition according to  claim 28 , wherein said whitening composition has a viscosity of between about 200,000 centipoise to about 600,000 centipoise. 
     
     
         30 . The tooth whitening composition according to  claim 28 , wherein said dental tray is a material selected from the group consisting of a thermoplastic resin and a thermoset resin. 
     
     
         31 . The tooth whitening composition according to  claim 28 , wherein the tooth whitening composition is contained in the dental tray. 
     
     
         32 . A tooth whitening composition having a viscosity of greater than 50,000 centipoise and less than 900,000 centipoise comprising:
 a whitening agent selected from the group consisting of peroxides, chlorites and hypochlorites;   a hydrophobic polymer carrier, and   an adhesion enhancing agent consisting of polyethylene gelled mineral oil that augments adhesion of said tooth whitening composition w tooth surfaces,
