12 Foods and Beverages That Will Stain Your Teeth

Berries

We love berries but have some bad news when it comes to your beauty goals. Due to their darker hues, berries may actually cause staining of the teeth when eaten regularly. To fight against the stains, consider brushing right after you enjoy your berries. "Make sure you're brushing twice a day, flossing daily, and using fluoride. Fluoride strengthens your teeth against those acid attacks caused by eating," says Dr. Kim Harms, spokesperson for the American Dental Association.
