Whiter Teeth ~Baking Soda and Lemon... This may be one of the most popular of the natural teeth whitening home remedies. The chemical reaction of baking soda with the citrus of lemon juice has a smile-brightening effect. Either one of these ingredients works well, but together they are super-effective.
Wedding-day white teeth! My dentist actually told me about this. Use a little toothpaste, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, 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.
