Teeth Whitening

Do-It-Yourself

While rubbing your teeth with banana peel, which contain such minerals as potassium, magnesium and manganese can whiten teeth, there are other -- perhaps neater -- ways to get rid of coffee and wine stains. "Over-the-counter products work very well on teeth that are a little yellow," says Dr. King. "If they are grey or brown, you really need something stronger."
