Abstract
An oral product and method is provided for inhibiting tartar formation on the teeth. The product is housed in a container and includes a first composition containing a water soluble calcium phosphate salt or monolithic combination of calcium and phosphate salts in a carrier with the first composition having a pH less than 7, and a second composition containing an alkaline material and a fluoride ion source in a carrier to achieve a pH greater than 7.5. The first and second compositions are separated from one another prior to use. When combined upon application to the teeth, the first and second compositions form a system for inhibiting tartar around the teeth.

- and
- (b) a second composition including from about 0.01 to about 30% by weight of an alkaline material and an anti-caries effective amount of a fluoride ion source, the second composition having a pH greater than 7.5 and stored separately from the first composition in a manner to avoid contact between the phosphate and the alkaline material.
A method for controlling dental tartar comprising:

- and
- (b) a second composition comprising from about 0.01 to about 30% by weight of an alkaline material and an anti-caries effective amount of a fluoride ion source, the second composition having a pH greater than 7.5 and stored separately from the first composition in a manner to avoid contact between the phosphate and the alkaline material;
- (ii) extruding a portion of first and second compositions onto a toothbrush;
- and
- (iii) brushing the teeth with the combination of first and second compositions.
