Abstract

A composition for the rapid, temporary whitening of teeth comprising an adhesive material and whitening particulates.

Claims

1. A rapid tooth whitening composition for imparting a natural white appearance to dental enamel comprising an adhesive and a whitening particulate comprising hydroxyapatite.

2. A composition according to claim 1, wherein the composition contains from about 0.1 to about 99% by weight of the adhesive, and from about 0.5 to about 60% by weight of hydroxyapatite.

3. A composition according to claim 1, wherein said adhesive comprises a polyorganosiloxane polymer.

4. A composition according to claim 1, wherein said adhesive comprises a siloxane pressure sensitive adhesive.

5. A composition according to claim 1, wherein said adhesive comprises a silicone resin.

6. A composition according to claim 1, wherein said adhesive comprises a polymer selected from the group consisting of natural resins, modified natural resins and pressure sensitive adhesives.

7. A composition according to claim 1, wherein said adhesive comprises a polymer selected from the group consisting of polyvinylpyrrolidone, polyvinylpyrrolidone/vinyl acetate copolymers and polyethylene glycol.

8. A dental strip comprising a layer comprising the composition according to claim 1, wherein said layer is operable to adhere to a surface of a tooth.

9. A liquid tooth whitening composition comprising the composition according to claim 1, wherein the liquid tooth whitening composition adheres to a surface of a tooth.

10. A method for whitening the surface of a tooth comprising applying a composition according to claim 1 to a surface of the tooth.

15. A composition according to claim 9, wherein said whitening particulate has an average diameter of from at least about 0.5 microns up to about 500 microns.

11. A rapid tooth whitening composition for imparting a natural white appearance to dental enamel comprising a siloxane pressure sensitive adhesive and a whitening particulate.

12. A composition according to claim 11, wherein said whitening particulate is comprised of one or more materials selected from the group consisting of calcium phosphate, titanium oxide, aluminum oxide, tin oxide, calcium oxide, magnesium oxide, polyethylene, polypropylene, a copolymer of ethylene/propylene, polytetrafluoroethylene, polyhexafluoropropene and combinations thereof.

13. A composition according to claim 11, wherein said whitening particulate is selected from the group consisting of:

tetracalcium phosphate, amorphous calcium phosphate, alpha-tricalcium phosphate, beta-tricalcium phosphate, hydroxyapatite and mixtures thereof.

14. A composition according to claim 11, wherein said siloxane pressure sensitive adhesive comprises a copolymer of polyorganosiloxane and silicone resin.

16. A method of imparting whiteness to a tooth in a mammal, the method comprising applying to the tooth a composition comprising a siloxane pressure sensitive adhesive and a whitening particulate.

17. A method according to claim 16, wherein said applying is achieved by contacting a film comprising said tooth whitening composition with a surface of a the tooth.

18. A method according to claim 16, wherein said applying is achieved by contacting a liquid form of said tooth whitening composition with a surface of the tooth.

19. A method according to claim 16, wherein said whitening particulate is comprised of one or more materials selected from the group consisting of calcium phosphate, titanium oxide, aluminum oxide, tin oxide, calcium oxide, magnesium oxide, polyethylene, polypropylene, a copolymer of ethylene/propylene, polytetrafluoroethylene, polyhexafluoropropene and combinations thereof.

20. A method according to claim 16, wherein said whitening particulate is selected from the group consisting of:

tetracalcium phosphate, amorphous calcium phosphate, alpha-tricalcium phosphate, beta-tricalcium phosphate, hydroxyapatite and mixtures thereof.

21. A method according to claim 16, wherein said siloxane pressure sensitive adhesive comprises a copolymer of polyorganosiloxane and silicone resin.

22. A method according to claim 16, wherein said whitening particulate has an average diameter of from at least about 0.5 microns up to about 500 microns.
