What is the term for a topical treatment that helps remineralize enamel by releasing fluoride?

• A. Fluoride gel
• B. Fluoride varnish
• C. Fluoride rinse
• D. Fluoride foam

Answer: (B)

Topical fluoride treatments differ in how long they stay on the tooth and how fluoride is released to the enamel. For remineralization, you want a method that adheres to the surface and delivers fluoride over time. Fluoride varnish is a resin-based coating painted onto the tooth that bonds to enamel and slowly releases fluoride. This prolonged contact delivers a high local fluoride concentration, helping to remineralize subsurface enamel lesions and protect against decay. Fluoride gel, rinse, and foam provide fluoride as well, but they don’t stay on the tooth or release fluoride as continuously, so they’re less effective for sustained remineralization. That sustained release is why fluoride varnish is the best term for this purpose.
