Keep teeth strong and dazzling white the natural way: eat fruit. Well not just any fruit, but fruits that contain malic acid including apples, strawberries and pineapples. Don't believe me? Drink a cup of tea, coffee or a dark soda. Then take a fresh strawberry, cut in half and rub the fruit across your teeth a few times. Voilà! The malic acid acts as an astringent and helps remove stains from enamel. Cool, huh?
Some suggest you mix the pulp of the fruit with baking soda as a tooth paste, but be aware that while this works amazingly well over time baking soda treatments can cause sensitivity and should be limited to a few times a week.
So when Mom said, "An apple a day keeps the doctor away" I guess she meant the dentist.
