Insight on Recent Reports on Fluoride and Community Water Fluoridation

A report was released early in the year in JAMA (Journal of the American Medical Association) that highlighted a systematic review and meta-analysis of 74 international studies on the impact of fluoride exposure, specifically on IQ. Questions were raised about the impact of this report on recommendations for products with fluoride, water fluoridation, and how to speak to parents and providers about the continued use of fluoride. Science still tells us that exposure to fluoride at the optimal level will help strengthen enamel and make it more resistant to cavities. Fluoride is safe.

The study did not review any US data, more than 2/3 of the reports were rated with high risk of bias, and the exposure amount noted was over 1.5 mg/L. The scientifically-recommended fluoride level for community water fluoridation in the U.S. is 0.7 mg/L. Regarding community water fluoridation in Idaho—with the exception of Mountain Home Air Force Base, NO public water system in the state adds fluoride. Any fluoride found in Idaho water occurs naturally.

Medical and dental providers may prescribe supplemental systemic fluoride to aid in oral health if indicated. Accessible for everyone, the best resource to determine the level of fluoride in a public water system is the CDC Website, My Water’s Fluoride, which tracks reported fluoride levels by state, by county, and by public water system. Supplements can be prescribed in liquid tablet, or lozenge form. The AAP recommends following the CDC fluoride supplemental dosage schedule. (See Table 2 in this AAP article.)
