There is even baking soda peroxide toothpaste which whitens your teeth. However, to whiten teeth you must stop smoking otherwise the stains will recur. Baking soda peroxide toothpaste gives you white teeth in a few weeks.
Most of the baking soda products are safe for use and can help fight cavities and reduce plaque.
Before you rush to buy a dozen baking soda tubes, try out a sample first. There are some people who have allergies to baking soda and may develop parched or dry lips. These individuals should refrain from baking soda products. Individuals who have sensitive teeth which hurt when the teeth are exposed to hot or cold foods, may find baking soda pastes too irritating and should avoid them. Or if you still want to try out such a tooth paste, look for a product with the lowest concentration of baking soda.
