What is Sodium fluoride?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Sodium fluoride which has developed particularly rapidly in recent years. Do you know about Sodium fluoride?
The official answer: Sodium fluoride is an ionic compound with the molecular formula NaF. It is a colorless crystal or white solid at room temperature and has no odor; it is also an important fluoride product and is widely used as wood preservative, wine sterilizer, electrolytic aluminum adjuster, dental fluoride, e
What’s the application of Sodium fluoride?
The application of NaF in toothpaste can play the role of anti-caries because fluoride can form fluorapatite on the surface of tooth enamel to improve the hardness and acid resistance of tooth enamel and reduce the formation of plaque to reduce the incidence of dental caries.
Fluoride toothpaste does have a certain anti-caries effect. As early as the middle of the 19th century, Europe already let pregnant women take calcium fluoride orally to prevent caries; by the 20th century, fluoride was recognized as an effective anti-caries agent worldwide. In general fluoride toothpaste, the content of sodium fluoride is 0.22-0.33%, and the content of sodium monofluorophosphate is 0.76%, such a tiny content is enough to have a good protective effect on human teeth, which can reduce the caries prevalence rate by 28%.
According to the different fluoride contained in toothpaste, fluoride toothpaste is divided into the following kinds: NaF toothpaste, sodium monofluorophosphate toothpaste, fluoride stannous toothpaste, fluoride amine toothpaste, and so on.
At present, the most common fluoride toothpaste in our market are NaF toothpaste and sodium monofluorophosphate toothpaste, or double fluoride toothpaste containing both NaF and sodium monofluorophosphate. Different kinds of fluoride toothpaste, no matter they contain single fluoride or double fluoride toothpaste, their anti-caries effect is the same.
