What is the primary function of sodium fluoride in toothpaste?
Apr 7，2026
Sodium fluoride is a common anti-cavity ingredient that forms fluorapatite on the surface of teeth, thereby enhancing enamel hardness and resistance to acid erosion. Additionally, it inhibits acid production by oral bacteria—reducing the incidence of tooth decay—and facilitates the remineralization and repair of early-stage demineralized enamel.
