The neat squeeze dispenser has a unique inner bag that empties itself as you squeeze in the middle. When the package gets lighter and is harder to squeeze, it's time to buy more Crest. Helps prevent ugly tartar build-up between dental cleanings, fights cavities with clinically proven Fluoristat, is gentle on tooth enamel. This product 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 on periodontal diseases. This produce contains no sugar, like all ADA Accepted toothpaste.
