How to brush your teeth with baking soda

In today's life, everyone has very high requirements for their own image, and always hopes to leave a better impression on others. However, once the teeth turn yellow, it will seriously affect our self-confidence and make our smile even more stingy. However, if we master some more methods in our daily life, we can also make our teeth whiter. Among them, brushing teeth with baking soda is the most common way. Let's learn how to brush teeth with baking soda.

How to Brush Your Teeth with Baking Soda

The principle and method of brushing teeth with baking soda:

Baking soda can clean teeth, but it will damage them. However, the fillings will not fall off.

Sodium bicarbonate (chemical formula: NaHCO3), commonly known as baking soda, is a white, fine crystal that is less soluble in water than soda. It decomposes to form sodium carbonate at 270℃. It is a strong base and a weak acid salt, and its aqueous solution becomes weakly alkaline due to hydrolysis. When it comes into contact with water, it releases a large amount of carbon dioxide to form small bubbles. In addition, the crystal shape of baking soda can be used as an abrasive, so it is very effective for cleaning.

Sodium bicarbonate is easily decomposed by heat. It will decompose rapidly above 65°C and completely decompose into carbon dioxide, water and sodium carbonate at 270°C. It is a commonly used leavening agent in food production:

2NaHCO3 → Na2CO3 + H2O + CO2

From this we can see that it is hydrolyzed into a weak alkaline in water. Because enamel contains phosphoric acid, during the demineralization process, if baking soda is used to brush your teeth, the weak alkalinity dissolved in the saliva will neutralize the phosphate ions in the enamel, causing the loss of calcium ions in the enamel, making the enamel gradually thinner, and of course destroying the tooth enamel.

Long-term use will make your teeth transparent, thus increasing your risk of having a mouth full of cavities. It is recommended that you directly purchase whitening toothpaste on the market because it is professionally formulated and can save you trouble.

The above is an introduction to how to brush your teeth with baking soda. After understanding it, we know that brushing your teeth and washing your face with baking soda can whiten your teeth, but if used frequently and for a long time, it can easily cause certain damage to the teeth. When we brush our teeth, we should try to choose fluoride toothpaste and use a softer toothbrush. This will have more benefits for the health of our teeth. In addition, we must insist on brushing our teeth in the morning and evening.
