At what age are supplements recommended for infants?

• A. 4 months and earlier
• B. 6 months and after
• C. 12 months
• D. 18 months

Answer: (B)

Fluoride supplementation in infants is generally considered once the child is about six months old. This timing aligns with when teeth begin to erupt and the child’s caries risk becomes more relevant, so supplementing can help support developing enamel without providing excess fluoride early on.

Whether supplementation is needed depends on the fluoride level in the local drinking water and the amount of fluoride the infant already receives from formula or breast milk. If the drinking water is adequately fluoridated, a supplement is usually not necessary. If the water has low fluoride, a clinician may recommend a fluoride supplement starting at six months and continuing as advised, to help prevent dental caries as the dentition develops. Starting earlier than six months is not typical, since the first teeth haven’t erupted yet and the risk/need for systemic fluoride is not established, and there is a risk of excessive fluoride exposure if given too soon.
