- Nice throw. - Dad! Dad! - Susie! - My checkup! Only one cavity. - Much better. - How'd you do it? - I brush with Crest now. - Toothpaste is toothpaste. - Mm-mmm. Crest has fluoride. Fluoride is the best cavity fighter around. Others we tried didn't have it. Announcer: While Crest can't promise only one cavity, we promise most people good checkups. Crest is accepted by the American Dental Association. - Class, now my favorite hold. Announcer: Fighting cavities is the whole idea behind Crest.
