ABSTRACT:
The use of polyphosphate in acidic oral compositions, especially acid beverages with a pH between 2.2 and 5.5, to alleviate or prevent the tooth damage associated with the consumption of acid. The invention may be practiced using polyphosphate alone or in combination with calcium and/or viscosity modifying polymers.
