Abstract
Abstract An oral composition such as a toothpaste (including gel or cream), mouthwash, lozenge, chewing gum or tooth powder containing a calculus-inhibiting amount of a linear molecularly dehydrated polyphosphate salt and, to inhibit enzymatic hydrolysis of said polyphosphate salt in saliva, a combination of a fluoride ion-providing source and a synthetic linear polymeric polycarboxylate.
