Chemical structure and properties
NaF crystallizes in the sodium chloride motif where both Na+ and F− occupy octahedral coordination sites. It is usually used as a reagent for the synthesis of fluorides. Representative substrates include electrophilic chlorides including acyl chlorides, sulfur chlorides, and phosphorus chloride. Like other fluorides, NaF finds use in desilylation in organic synthesis.

Dental Care: Sodium fluoride is widely used in toothpaste, mouthwash, and professional dental treatments as a key ingredient for preventing tooth decay.
Water Fluoridation: Many municipal water supplies are fluoridated by adding sodium fluoride to the water. This process is a public health measure to improve dental health in the community by reducing the incidence of cavities.
Topical Fluoride Treatment: Dentists often apply topical fluoride treatments to patients’ teeth to provide additional protection against cavities. This can be done as a gel, foam, or varnish.
Industrial Applications: Sodium fluoride is used in various industrial processes, including in the production of aluminum, steel, and glass. It can act as a flux to lower the melting point of certain materials and improve their flow properties.
Pesticides: In agriculture, sodium fluoride has been used in some pesticide formulations. However, its use in this context has been decreasing due to environmental and health concerns.
Insecticides and Rodenticides: Although not as common as other compounds, sodium fluoride has been used in some insecticides and rodenticides to control pests.
Ceramic and Glass Industry: In the ceramic and glass industry, sodium fluoride can be used as a flux to lower the melting point of materials, allowing for easier shaping and forming.
