- 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.
