Girl: Back at school, Ann was a terrific volleyball player. (cheering) Lucky for me, I was always on her side. Once though we were on opposite sides in a toothpaste test. For three years each side brushed with a different toothpaste. And mine reduced cavities 21%. Later we learned it was Crest. Ann's side had the same toothpaste but without Fluoristan. Now it's regular checkups, watch between meal treats, brush often with Crest. 

Narrator: Crest reduced cavities 21% in this test. In a similar test 34%. And in still another test where everyone brushed three times a day, Crest reduced cavities 46%, almost half. This seal and statement signify that Crest Toothpaste is accepted by the Council on Dental Therapeutics of the American Dental Association. Crest, proved effective against cavities.
