Are teeth whiteners bad for you? I like to use the stripsa lot.
Teeth-whitening is all the rage—increasing threefold over the past few years—for those who want a winning smile. Whether in the doctor’s office or at home, it is safe and effective, says Dr. Debra Gray King, dentist and president of the Atlanta Center for Cosmetic Dentistry. In over-the-counter treatments (like the strips you use), peroxide bleaches your pearly whites. While it doesn’t eat at tooth enamel, the chemical can penetrate nerves and cause temporary pain or sensitivity. Kids have less stains on their choppers, and those under 12 should ask a dentist before whitening. Besides, your teeth will reach a point at which they are as white as they can get, so save your allowance.
