1. Going rogue with whitening
Don’t start bleaching your teeth until you’ve seen your dentist. She can determine if you’re a good candidate for whitening, and prep your mouth for the process. “The best time to bleach is right after a dental cleaning because the tooth’s surface is clean,” says prosthodontist Francine Albert. A follow-up appointment a few weeks later will allow your dentist to see how you’re doing, and if you need a desensitizing agent such as a topical fluoride to alleviate any tooth sensitivity.
