Abstract: In an anticalculus oral composition containing in an orally acceptable vehicle one or a mixture of water soluble linear molecularly dehydrated alkali metal or ammonium polyphosphate salts as essential anticalculus agent, an amount of a fluoride ion source sufficient to supply about 25 ppm to about 2,000 ppm of fluoride ions, and one or a mixture of water soluble alkali metal or ammonium synthetic anionic polymeric polycarboxlate salts, the improvement comprising employing in said composition a polyphosphate ion:polycarboxylate salt weight ratio ranging from about 0.3:1 to about 2.5:1.
