Sodium fluoride is widely used in dental care products like toothpaste and mouthwash to prevent tooth decay and strengthen enamel. It is also added to public water supplies in a process called water fluoridation to improve dental health across communities. Additionally, it is employed in the manufacturing of ceramics, glass, aluminum, and other metallurgical processes as a flux to lower melting points and improve material properties. In some cases, it is used as a pesticide to control pests in agricultural and industrial settings.
