- If you're serious about reducing your family's cavities, this smile can help you. It belongs to Doug Gulick, one of thousands who tested toothpaste and showed Crest reduces cavities. Doug? 

- Our toothpaste test lasted two years. 

- And half the group used Crest and the other half used regular toothpaste. 

- Yes, sir. 

- Did you brush in any special way? 

- No, sir. 

- What were the results? 

- 25% fewer cavities. 

- For your group? 

- Yes. 

- And you used Crest. 

- Mm-hmm. 

- Such results show why Crest is recognized effective against cavities by the American Dental Association. As their council reports, "Crest has been shown to be an effective decay-preventive dentifrice that can be of significant value when used in a conscientiously applied program of oral hygiene and regular professional care." Protect your family with good dental habits, dental checkups twice a year, and Crest, the only toothpaste recognized effective against cavities by the American Dental Association.
