Abstract
The anticariogenic activity of fluorine-containing compounds in oral compositions also containing zeolitic zinc ions is retained at advantages levels over protracted periods of time by adjusting the pH of the composition to the range of 9.5 to 11. The zeolite not only provides desired Zn.sup.++ ions to the formulation with minimal adverse affect on the active fluoride content but also is found to be an exceptionally good abrasive and/or polishing agent.
