Original Note:
The US PHS recommends a fluoride concentration of just 0.7 mg/L in drinking water: https://www.cdc.gov/fluoridation/about/community-water-fluoridation-recommendations.html The JAMA paper: “In 31 studies reporting fluoride measured in drinking water, a dose-response association was… null at less than 1.5 mg/L.” So the PHS recommendation doesn’t need reassessment.
