ABSTRACT:
Specific compositions and methods are disclosed employing calcium fluoride inhibitors in two-component fluoride delivery systems to produce an initial delay in calcium fluoride formation and to control the rate of reactions that precipitate calcium fluoride in order to achieve enhanced fluoride deposition in the oral environment. In the two-component fluoride delivery system, one component contains a source of calcium ions and the other a source of fluoride ions. An inhibitor of calcium fluoride formation is present in one or both phases such that when one or both components are mixed the formation of calcium fluoride precipitate does not occur until at least about five seconds after mixing. The system may be employed in the form of mouth rinses, dentifrices, or chewable tablets.
