- Hi, Mr. Goodwin! - Holy smokes Nancy, that's some microscope. - I won first prize at the science fair. - Congratulations, and what can I do for you professor? - (giggles) Well, I need some toothpaste. - Well, here's the Crest. - No, this one's fine Mr Goodwin. - Nancy, how have your checkups been? - Not terrific. - You have a scientific mind, right? - Right. - Okay. Take the fact that Crest has fluoride, does your toothpaste? - No. - Does your toothpaste have over 20 scientific tests that prove it reduces cavities? - Uh-uh. - The fact is Nancy, you can't buy a better cavity fighter than Crest. - Tell you what Mr. Goodwin, I'll use Crest for six months and my dentist will tell us the results. - Mr. Goodwin, the results are in and Crest really helped! I just had a great checkup. - That result doesn't surprise me at all! (chuckling) - Narrator] New regular flavor Crest tastes even better. Look for new improved, regular flavor Crest where you buy toothpaste.
