Abstract
Abstract An improved method for the control of calculus is disclosed employing one or more insoluble zinc compounds as the active agent. Dentifrice formulations and mouthwash formulations for use in the novel method are also disclosed. The mouthwash compositions comprise from 1/10% to about 25% by weight of the zinc compound while the dentifrice compositions comprise 1/4% to about 25% by weight of said compound.
