Abstract

Disclosed is a method for cleaning teeth including extruding a first semi-solid component including hydrogen peroxide as an active ingredient, and extruding a second semi-solid component comprising sodium bicarbonate as an active ingredient, the first and second components being suitable for oral use. The first component and the second component are placed in contact with each other on a toothbrush. The teeth are brushed using the first and second components concurrently as a cleaning medium.

Claims

1. A method for cleaning teeth comprising extruding a first semi-solid component comprising hydrogen peroxide as an active ingredient, said first component being suitable for oral use;

extruding a second semi-solid component comprising sodium bicarbonate as an active ingredient, said second component being suitable for oral use;

placing said first component and said second component in contact with each other on a toothbrush; and

brushing said teeth using said first and second components concurrently as a cleaning medium.

2. The method of claim 1, wherein said first and second components are extruded together.

3. The method of claim 1, wherein said first and second components are extruded together on the toothbrush.

4. The method of claim 1, wherein said first and second components are extruded and placed on the brush separately.

5. The method of claim 1, wherein said brushing takes place immediately after extruding said components and placing them onto said toothbrush.

6. The method of claim 1, wherein said first component contains from about 0.1 to about 10 percent H₂ O₂.

7. The method of claim 1, wherein said first component is a non-neutralized gel.

8. The method of claim 1, wherein said first component is a neutralized gel.

9. The method of claim 1, wherein said second component contains from about 2 to about 60 percent sodium bicarbonate by weight.

10. The method of claim 1, wherein said second component is a paste.

11. The method of claim 1, wherein said first component is a gel comprising as a gelling agent a member selected from the group consisting of (a) copolymers of acrylic acid cross-linked with polyallyl sucrose;

(b) an organic polymeric acid colloid; and

(c) a polyoxyethylene/polyoxypropylene block copolymer.

12. The method of claim 1, wherein said second component is a paste comprising a thickener/stabilizer.

13. The method of claim 12, wherein said paste component further comprises a bodying agent.

14. The method of claim 12, wherein said paste component further comprises an additional tooth-cleaning agent.

15. The method of claim 12, wherein said paste component further comprises a fluorine-containing compound having anti-caries activity.

16. The method of claim 7, wherein said gel component further comprises a copolymer of acrylic acid cross-linked with polyallyl sucrose as a gelling agent.

17. The method of claim 8, wherein said gel component further comprises a copolymer of acrylic acid cross-linked with polyallyl sucrose as a gelling agent and a polyol selected from the group consisting of glycerin, sorbitol, propylene glycol, polypropylene glycol, polyethylene glycol, an ethoxylated lower fatty alcohol and a propoxylated lower fatty acid alcohol.
