Fights cavities plus fights tartar build-up. Contains Fluoristat for effective cavity protection. Special tartar blockers provide clinically proven effective tartar prevention. Once formed, tartar can only be removed by dental cleaning. Crest Tartar Protection's Special Tarter Blockers help stop new tartar build-up before it forms. This product contains no sugar, like all ADA accepted toothpastes. ADA Accepted (American Dental Association): Crest Tartar Protection has been shown to be an effective decay-preventive dentifrice that can be of significant value when used as directed in a conscientiously applied program of oral hygiene and regular professional care. It has been shown to reduce the formation of tartar above the gumline, but has not been shown to have a therapeutic effect of periodontal diseases. - Council on Scientific Affairs, American Dental Association.
