A glance at a store's toothpaste selection can make your head spin. Narrow the choices by checking for the American Dental Association (ADA) seal of approval. Then try this guide:
- Pastes with mouthwash offer no advantage in beating bad breath, says Matt Messina of the ADA.
- All pastes contain a polisher and an abrasive. Baking soda is both. Choose this only if you prefer the taste.
- Whitening pastes won't get your teeth as white as if they'd been bleached, but they will brighten them more than a standard toothpaste, says Samuel Yankell, a dental scientist at the University of Pennsylvania.
- Kids don’t need their own toothpaste. And most don’t develop tartar until puberty, so a fluoride paste is enough, says Messina.
- Sensitive teeth? Potassium nitrate on the label means this paste will help block your teeth's pain receptors.
