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.

Claims (16)

1. A tooth whitening system comprising:

a dental tray having a surface operable to confront a tooth surface; and

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.

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

3. A system according to claim 1 , wherein said dental tray is a material selected from the group consisting of: a thermoplastic resin and a thermoset resin.

4. A system according to claim 1 , wherein the tooth whitening composition is contained in the dental tray.

5. A tooth whitening system consisting of:

a dental tray having a surface operable to confront a tooth surface; and

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 to tooth surfaces.
