Fluoride varnishes are available in the United States, and the Federal Drug Administration has approved a fluoride varnish for use as a cavity preparation lining varnish and as a tooth desensitizing agent. The literature, however, supports the use of fluoride varnishes to inhibit tooth demineralization and enhance remineralization. The purpose of this paper is to present an overview of literature and make recommendations according to the available scientific evidence. Findings support the use of fluoride varnishes as a safe and effective topical fluoride agent.
