Fluoride therapy is a dental treatment that involves the application of fluoride to help prevent tooth decay. Fluoride is a natural mineral that strengthens tooth enamel, making it more resistant to acid attacks from bacteria and sugars. This therapy is often recommended for children and adults at higher risk of cavities. The treatment can be administered in various forms, including fluoride varnish, gels, or mouth rinses. Dentists may apply fluoride during routine check-ups, and it can also be found in some toothpaste and drinking water. Regular fluoride therapy can significantly reduce the incidence of cavities and improve overall dental health.
