Abstract
Abstract A dentrifice containing a limited amount, 0.001-0.05% by weight, of titanium tetrafluoride, and preferably at least 0.5% by weight xylitol or 0.01% by weight saccharin, is applied to a person's teeth to limit the adherence of plaque to the teeth. The method finds particular advantage when used as a liquid in conjunction with cavitation cleaning of the teeth.
