Abstract
A method and a composition for retarding calculus are disclosed. The composition includes aluminum compounds, which when titrated with NaF have an F/Al ratio of about 1.2 or greater, in combination with an orally acceptable vehicle. The vehicle is compatible with the aluminum compound used and with the pH desired. The method generally includes applying the aluminum compound at a pH of less than about 4.5 to the site of the calculus.
