Go for Fluoride Toothpastes
To prevent decay and kill bacteria, look for a toothpaste with fluoride, which can help prevent gum disease and decay, and strengthen tooth enamel. "It's also very important to chose toothpastes that have the American Dental Association Seal of Acceptance. This shows that it has been evaluated by someone other than the manufacturer and is safe and effective," Cram says. She recommends Colgate Total Advanced Deep Clean Toothpaste ($8; amazon.com).
