A 4-year-old patient lives in an area with non-fluoridated water (fluoride content less than 0.3 ppm). According to the current ADA fluoride supplementation schedule, what is the recommended daily dose for this child?

Per the current ADA dietary fluoride supplement schedule, children aged 3–6 years living where water fluoride is below 0.3 ppm should receive 0.50 mg fluoride per day. (Children 6 months–3 years at that same low water-fluoride level get 0.25 mg/day, and children 6–16 years get 1.0 mg/day.) A 4-year-old falls into the 3–6 year bracket.
