Abstract
Oral compositions and a method for inhibiting tartar on teeth, said compositions comprise a fluoride source, a dental abrasive, and an antihydrolysis agent selected from homopolymers of substituted acrylamides, homopolymers of unsaturated sulfonic acids and salts thereof, and homopolymers and copolymers of cationic monomers. The antihydrolysis agents have molecular weight of 100 to 100,000 and inhibit hydrolysis of polyphosphates to orthophosphates. Whereas polyphosphates generally are effective in inhibiting formation of tartar on teeth, orthophosphates are relatively ineffective.
