Abstract:
1. A method of enhancing protection of teeth against caries and cavities and increasing resistance to acid demineralization associated with caries processes comprising administering to a subject's oral cavity an oral care composition comprising a combination of (a) a phosphonate group containing copolymer or cotelomer that is substantive to teeth and provides increased hydrophilic character to teeth surfaces and (b) one or more fluoride ion sources to provide enhanced fluoride incorporation into and remineralization of the subject's teeth, wherein the phosphonate group containing copolymer or cotelomer has an average molecular weight of from about 3,000 to about 60,000 and is prepared by copolymerizing a phosphonate containing monomer selected from vinyldiphosphonic acid, vinylidene-1,1-diphosphonic acid, 2-(hydroxyphosphinyl)ethylidene-1,1-diphosphonic acid) or salts thereof with at least one other monomer selected from acrylic acid, methacrylic acid or salts thereof.
