Fluoride varnish is used for in pediatric dentistry?

• A. Desensitize dentin
• B. Disinfect
• C. Whiten teeth
• D. Remineralize enamel and prevent caries

Answer: (D)

Fluoride varnish is used primarily to remineralize enamel and prevent caries. The varnish delivers a high concentration of fluoride directly to the tooth surface, promoting the formation of fluorapatite and enhancing enamel resistance to acid while aiding the repair of early, subclinical demineralization. This makes it especially useful for children at high risk for decay or with newly erupted teeth, applied periodically to maintain protection. It does not disinfect surfaces or whiten teeth, and while there can be some desensitizing effect if dentin is exposed, its main goal in pediatric care is caries prevention through remineralization.
