When is oral fluoride supplementation indicated?

• A. Wait until age 3 to start supplementation
• B. Start supplementation in all cases
• C. Begin only if there is dental caries
• D. Start supplementation when local water supplies are fluoride deficient

Answer: (D)

Fluoride supplementation is a targeted preventive measure based on environmental fluoride exposure. It is considered when a child’s fluoride intake from drinking water is insufficient to meet preventive needs. If the local water supply is fluoride deficient, providing fluoride systemically helps achieve the recommended intake and supports enamel remineralization to reduce caries risk. When the water already provides adequate fluoride, additional supplementation isn’t needed and could raise the risk of fluorosis with excess intake. The exact starting age and dose depend on age and the water’s fluoride level, but the core rule here is that supplementation is indicated only when the water is deficient.
