To whiten your teeth, all you need is baking soda, also known as bicarbonate of soda, which you most likely already have in your kitchen or refrigerator. Baking soda is an inexpensive and efficient home treatment for tooth whitening. It can be used instead of more expensive products like toothpastes or powders. Baking soda has a number of benefits for cleaning and beautifying your body. It can be used as a drain cleaner, floor polish, insecticide, deodorizer, and dog chew treat. It is also useful for getting rid of ringworms and other fungal infections on skin, nails, and hair. Finally, it can be used as a mild abrasive when mixed with water and applied to a dry face for cleansing. This mixture can then be washed off with more water when needed. Baking soda is very easy to use and does not cause any harm even if used excessively. It is safe for babies, children, adults, and animals. There are no interactions with other medications so using it will not make anything else you are taking work differently. It will not cause any side effects unless you have an allergy to it or are allergic to yeast. In this case, the symptoms will be similar to those of a cold or flu. The only problem with baking soda is that it does not last long enough to be considered a treatment option for acne.
