What is the purpose of a fluoride varnish application?

The purpose of a fluoride varnish application is primarily to provide a concentrated fluoride treatment aimed at preventing tooth decay. Fluoride is known for its ability to enhance the remineralization process of the enamel and inhibit the activity of cavity-causing bacteria. When applied as a varnish, it adheres to the tooth surface, allowing for prolonged exposure to fluoride, which is particularly beneficial for patients at higher risk of developing caries.

The use of fluoride varnish is a proactive measure in dental health, targeting both children and adults to bolster their defenses against tooth decay. This is especially effective in areas where there might be early signs of decay or where the enamel is demineralized. It is not designed for cosmetic purposes like whitening teeth or removing stains, nor does it serve to seal chipped teeth or replace lost enamel, as these require different dental interventions.
