Lindsay says she is "obsessed" with bleaching her luminous smile, and she's done it every day for the last three years. Dr. Oz says when you bleach your teeth—the most common cosmetic procedure in the United States—hydrogen peroxide is used to remove stains and make your teeth appear whiter.
While teeth whitening is safe, Dr. Oz says there are some dangers. Some whitening products can take off your teeth's enamel and wear it so thin that you can actually see through your teeth. Your gums can also be damaged.
"You should limit yourself to a two-week treatment, or a really great idea is to get a dentist to do it and then follow it up with a week or two of doing it yourself, but doing it every day is a mistake," Dr. Oz says. Instead of whitening your teeth every day, you should floss.
