Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two.
Baking soda teeth whitener. This does work and fast too! A couple of days before my wedding I put toothpaste on my toothbrush and sprinkled a little pile of baking soda on top and brushed with it. Tastes pretty gross but you will notice results within even a day or two.
