Fluoride varnish is classified as what type of treatment?

Fluoride varnish is classified as a therapeutic treatment because it is used to manage and prevent dental caries through the application of fluoride to the tooth surfaces. The varnish acts by enhancing the process of remineralization, which helps to strengthen the enamel and makes it more resistant to decay. This therapeutic approach is aimed at treating or preventing existing conditions rather than simply being a preventive measure, which typically focuses on actions taken to avoid the onset of disease altogether.

In addition, while fluoride varnish does have preventive qualities, its main classification within the context of dental treatments is therapeutic due to its direct role in addressing existing levels of demineralization and providing a treatment that supports the health of the teeth. Other treatments such as restorative procedures would involve repairing or restoring the function of teeth after damage has occurred, whereas diagnostic treatments focus on identifying issues rather than actively treating or preventing them.
