The problem with commercial teeth whiteners is that they contain chemicals that can enter your system. Luckily, there are some more natural ways to whiten and clean your teeth.
1. Baking soda. Be sure to get an aluminum-free baking soda, dampen a toothbrush, dip it into the baking soda, and brush away. This is most effective when you use small circular motions with the brush on each individual tooth. Rinse mouth well afterward.
2. Eat strawberries and oranges. According to Dr. Andrew Weil in a recent appearance on the Dr. Oz show, these fruits contain enzymes which can whiten teeth by eating away at the plague and stains. Who would have thought that eating fruit could help whiten your teeth?
