- Oh, Mr. Goodwin, what do you know about these new fluoride toothpastes? 

- Not as much as I know about Crest. 

- Oh, seriously? 

- I am serious. That's why I like Crest. It's got proof it works. 

- Like what? 

- Tests with kids like yours, research with kids like yours. Crest has been tested under more conditions than any other toothpaste to prove it fights cavities. 

- You've proved your point, Mr. Goodwin. 

Announcer: Crest is accepted by the American Dental Association. 

- You can't beat Crest for fighting cavities.
