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.
