What are the functions and effects of baking soda toothpaste?

Toothpaste is an indispensable daily necessity in life, because people need to brush their teeth every day. If you don’t brush your teeth for a long time or develop bad brushing habits, you may have many dental problems, not just caries and toothache. Now there are many types of toothpastes to choose from on the market, so what are the functions and effects of baking soda toothpaste?

Let’s start with baking soda, which is sodium bicarbonate (NaHCO3). It is a healthy product that is easily soluble in water, has a salty taste, and is weakly alkaline.

Baking soda toothpaste is a toothpaste that uses baking soda as the main abrasive. The main ingredients of toothpaste are: abrasive (the main ingredient of toothpaste), surfactant (for cleaning and foaming) and excipient binder (used to bind these powders into the shape of toothpaste).

Ordinary toothpastes on the market, low-end ones mostly use calcium carbonate as an abrasive, while mid- to high-end ones mostly use hydrated silica. Both are insoluble in water and remain particulate during brushing, which naturally wears down your teeth.

The baking soda toothpastes on the market are all high-end functional toothpastes that use high-quality ultra-fine baking soda materials. The baking soda dissolves in water when brushing your teeth and is combined with surfactants. Therefore, the effect of abrasives on teeth wear is minimal during the entire brushing process.

Researchers pointed out from the beginning that the acidic pH of the mouth is the culprit for tooth decay. The pH value of 5.5~5 is considered to be the critical value for tooth demineralization. It shows that alkaline baking soda (pH 9), especially when used as a mouthwash, can help maintain a healthy pH in the mouth.

Studies comparing toothpastes with and without baking soda have found that those containing sodium bicarbonate are significantly more effective at removing plaque — especially in hard-to-reach areas. It also acts as a chelating agent and antiseptic against most oral pathogens.
