(military marching chant) Narrator: Back at Howe Military School, we always marched together. (marching chant) Well, almost always. Once we were split up on purpose for a toothpaste test. Each group brushed three times a day for two years, but with a different toothpaste, and mine reduced cavities 46%, almost half. Later we learned it was Crest. The others use the same toothpaste, but without fluoristan. Since then, it's regular checkups, watch between meal treats and brush often, with Crest. Narrator 2: The Council and Dental Therapeutics of the American Dental Association says, "Crest has been shown to be an effective decay-preventative dentifrice, that can be a significant value when used in a conscientiously applied program of oral hygiene and regular professional care." Narrator: Crest, reduced cavities 46% for my group.
