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.

First claim

What is claimed is:

1. 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 pressure-sensitive, hydrophobic polymer carrier comprising silicone 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.

2. The tooth whitening composition according to claim 1 , wherein said whitening composition has a viscosity of between about 200,000 centipoise to about 600,000 centipoise.

3. The tooth whitening composition according to claim 1 , wherein the tooth whitening composition is contained in a dental tray.

4. The tooth whitening composition according to claim 3 , wherein said dental tray is a material selected from the group consisting of: a thermoplastic resin and a thermoset resin.

5. A tooth whitening composition having an overall viscosity of greater than 50,000 centipoise and less than 900,000 centipoise, comprising:
between about 0.1 to about 1 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 silicone 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.

6. The tooth whitening composition according to claim 5 , wherein said whitening composition has a viscosity of between about 200,000 centipoise to about 600.00 centipoise.

7. The tooth whitening composition according to claim 5 , wherein the tooth whitening composition is contained in a dental tray.

8. The tooth whitening composition according to claim 7 , wherein said dental tray is a material selected from the group consisting of: a thermoplastic resin and a thermoset resin.
