Sodium fluoride (NaF)

Sodium fluoride (NaF) is a chemical compound commonly used in dental care to strengthen tooth enamel and prevent cavities. It contains sodium, a type of salt, and fluoride, a mineral known for its benefits in oral health. When applied to teeth, fluoride helps reinforce the enamel—the outer protective layer—making it more resistant to acid attacks from food and bacteria. NaF is often found in toothpaste, mouth rinses, and professional dental treatments. While primarily beneficial for oral health, it is important to use fluoride products as directed to avoid overexposure.
