Yes. Baking soda is an alkaline substance that has the effect of whitening teeth. This mild abrasive substance can wash away plaque and stains on the surface of teeth.

Baking soda, scientific name is sodium bicarbonate, becomes weakly alkaline when dissolved in water, with a pH value of around 8. In daily life, it is often used as a leavening agent in food production. Some people also use it to scrub dirt in stainless steel pots, copper pots or iron pots, as well as thermos bottles.

Brushing your teeth with baking soda will not affect your gums or oral cavity. Because baking soda will dissolve quickly when it meets water, and after people eat, the oral environment is mostly acidic. When baking soda meets acid, it will form carbonic acid (carbon dioxide water) and sodium ions. These three substances are harmful to the oral cavity. There is no harm.

It should be reminded that people suffering from oral ulcers and gingivitis are 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 will help change the chemical structure of the coffee or tea beverage, making it difficult for the pigment to adhere to the surface of the teeth, preventing the teeth from turning black and yellow.

2. Eat more dark green vegetables. The minerals contained in spinach, broccoli and other dark green vegetables help form a protective film on the tooth surface to prevent tooth discoloration. Dr. Thomas Connelly, an expert in cosmetic dentistry in New York, USA, also recommends eating more apples, pears, celery and carrots. Chewing can promote saliva secretion, reduce oral bacteria and whiten teeth.

3. Rinse your mouth for 30 seconds after each meal. Dr. Connelly recommends rinsing your mouth for 30 seconds after eating to help prevent tooth discoloration caused by food pigments and to remove food residue from the mouth.

4. Use a straw to drink drinks. Drinking large amounts of carbonated drinks can easily damage tooth enamel, causing tooth discoloration and tooth decay. It is recommended to use a straw when drinking such drinks. ?
