Baking soda, the scientific name of sodium bicarbonate, is weakly alkaline after being dissolved in water, and its pH value is about 8. In our daily life, it is often used as a leavening agent in the process of food production, and some people will use it to scrub the dirt in stainless steel pot, copper or iron pots and thermos bottles.
Brushing your teeth with baking soda will not affect your gums and mouth. Because baking soda dissolves quickly when it meets water, and after people eat it, the oral environment is mostly acidic. When baking soda meets acid, it will form carbonic acid (carbon dioxide+water) and sodium ions, which is harmless to the mouth.
Need to be reminded that people with oral ulcers and gingivitis, it is best not to use it, otherwise it will easily aggravate the condition.

Other natural ways to whiten teeth are:
1, drink coffee with some milk. When drinking tea or coffee, adding some milk is helpful to change the chemical structure of coffee or tea beverage, so that pigment is not easy to adhere to the surface of teeth and prevent teeth from turning black and yellow.
2. Eat more dark green vegetables. Minerals contained in dark green vegetables such as spinach and broccoli help to form a protective film on the tooth surface to prevent tooth discoloration. Dr Thomas Connery, an expert in cosmetic dentistry in new york, USA, also suggested eating more apples, pears, celery and carrots. Chewing can promote saliva secretion, reduce oral bacteria and whiten teeth.
