Should your toothbrush have soft, medium or hard bristles?

The next time you buy a toothbrush – make sure it’s labeled “soft.” 

Dental Professor Dr. Mark S. Wolff says NEVER choose hard bristles, they can really do some damage. Medium might be okay but they’re often too harsh. You’ll also want angled bristles. Toothbrushes with bristles going in different directions do a much better job getting into the crevices. A bent neck is better than straight and a smaller head does a better job in the back of your mouth.
