Crest toothpaste commercial - 1970's

Dad, Terry, I only had one cavity. That's my boy. How'd you do it, kid? Tell him, Terry. We switched to Crest. Are you sure it was a Crest? Now I am. That fluoride stuff works. The others we tried didn't have it. And Crest is accepted by the American Dental Association. Looks like you have a winning formula, coach. Fighting cavities is the whole idea behind Crest.
