What is the recommended fluoride supplementation for children ages 6-16 years in areas where water fluoridation is below 0.3 ppm?

The recommended fluoride supplementation for children ages 6-16 years in areas where water fluoridation is below 0.3 ppm is 1.0 mg/day. This recommendation is based on the need to provide additional fluoride to help prevent dental caries, especially in children who may not be receiving adequate amounts from their local water supply. At this age, children are still developing their permanent teeth, making them particularly susceptible to decay, so appropriate levels of fluoride can significantly contribute to the remineralization of enamel and protection against cavities.

The guidance for fluoride supplementation takes into consideration the concentration of fluoride present in the local water supply, as well as the dietary intake of fluoride from other sources, such as toothpaste and dietary supplements. In areas with low water fluoridation levels, a higher daily supplemental dose, such as 1.0 mg, is warranted to ensure that children have a sufficient level of fluoride to support oral health. Other options may not provide enough fluoride to meet the protective needs of children in these low-fluoride areas.
