Sodium fluoride is a chemical compound composed of sodium and fluoride ions, represented by the formula NaF. It is commonly used in dental care products, such as toothpaste and mouth rinses, to help prevent tooth decay by strengthening tooth enamel. In addition to its dental applications, sodium fluoride is also used in some industrial processes and as a pesticide. It is important to handle sodium fluoride with care, as excessive exposure can be harmful. Regulatory agencies monitor its use to ensure safety in consumer products and environmental applications.
