From birth to 6 months, how much fluoride supplementation can you receive?

• A. 0.3 ppm
• B. none
• C. 0.5 mg/day
• D. 1.0 mg/day

Answer: (B)

From birth to six months, no fluoride supplementation is indicated. At this stage, a baby’s fluoride intake should come from natural sources such as breast milk or formula prepared with water, and starting a fluoride supplement could lead to excessive fluoride exposure during early enamel development. To avoid the risk of dental fluorosis, guidelines specify that supplementation is not given in the first six months. After six months, supplementation may be considered only if the drinking water has low fluoride (for example, less than 0.3 ppm) and the child’s caries risk warrants it, with the appropriate dose based on age and water fluoride level.
