Nt Clear Varnish (Denbio) 5% Sodium Fluoride Varnish is a dental treatment designed to help protect teeth from cavities and decay. This varnish contains 5% sodium fluoride, which is a highly effective agent in remineralizing tooth enamel and preventing tooth decay. The varnish is applied directly to the teeth by a dental professional and forms a protective layer that slowly releases fluoride over time. The apple-flavored varnish is easy to apply and is particularly beneficial for patients, including children, who are at higher risk of tooth decay. The treatment is commonly used in dental clinics as part of routine care to maintain oral health.
