At which age group are fluoride drops best for children?

• A. 0-2 years
• B. 3-5 years
• C. 6-8 years
• D. 9-12 years

Answer: (A)

Fluoride delivered systemically is most effective when teeth are forming, so it can become part of the developing enamel. Primary teeth begin forming (even before birth) and continue to form through the first couple of years of life. Providing fluoride drops during that early window helps incorporate fluoride into the enamel of those teeth, making them more resistant to decay as they erupt. By the time older children reach beyond the early years, much of the enamel formation is complete, so the additional benefit from systemic fluoride is smaller and topical fluoride becomes more important. For this reason, fluoride drops are best suited to the youngest age group, around 0–2 years, with careful dose monitoring to avoid fluorosis.
