Sodium fluoride, commonly known as NaF, is a chemical compound made up of sodium and fluoride ions. It appears as a white, odorless solid and is often used in various applications, including dental care products like toothpaste and mouth rinses. NaF helps to prevent tooth decay by strengthening tooth enamel and making it more resistant to acid attacks from bacteria. In addition to its dental uses, NaF is also employed in industrial processes, such as metal treatment and glass production. It can be found in some water fluoridation programs aimed at improving public dental health. However, excessive exposure to NaF can be harmful, so it is important to use it responsibly.
