For fluoride varnish scheduling, which statement is true?

• A. Every 12 months
• B. Weekly
• C. Only once
• D. Every 3–6 months, depending on risk

Answer: (D)

Scheduling fluoride varnish is about matching how often it’s done to a child’s caries risk. Fluoride varnish provides a quick, safe topical dose of fluoride that helps strengthen enamel and prevent new decay, making it a practical preventive step during regular well-child or dental visits. Because risk varies—from low to high—the frequency should be tailored. The best approach is to apply varnish every 3–6 months, with more frequent applications for higher-risk children and less frequent for lower-risk children. This balances ongoing protection with practical care.

Choosing a yearly interval misses opportunities to prevent decay in higher-risk kids, while a weekly or a one-time application isn’t sufficient for ongoing caries prevention.
