The role of Sodium Fluoride NaF in toothpaste
Sodium Fluoride NaF is a chemical product containing fluorine, so we all know that one of the ingredients in the toothpaste we use in our daily life is Sodium Fluoride NaF, so what role does sodium fluoride play in toothpaste? I believe that many people do not understand, so today I will share with you the knowledge of this.
Sodium Fluoride NaF is a colorless bright crystal or white powder with a melting point of 993°C, a boiling point of 1695°C and a specific gravity of 2.25. soluble in water. Brushing your teeth with fluoride toothpaste is one of the effective oral health care measures to prevent caries. It can reduce the caries rate by up to 28%. Generally, the content of sodium fluoride in fluoride toothpaste is 0.22%. It plays a role in promoting remineralization during the remineralization process. Therefore, brushing your teeth with fluoride toothpaste 1-2 times a day helps to deposit calcium fluoride on the surface of tooth enamel, and has obvious effect of preventing caries.
When brushing teeth, a large number of fluoride ions form calcium fluoride particles on the surface of enamel, which constitute a fluoride pool between plaque and enamel, which can reduce the solubility of hydroxyapatite in enamel, increase the anti-caries of teeth, and increase the hardness of enamel. , thereby improving the integrity of the enamel.
The above is the relevant introduction about the application of Sodium Fluoride NaF in toothpaste, I hope it can help everyone.
