Proposed HHS Recommendation for Fluoride Concentration in Drinking Water for Prevention of Dental Caries
The Department of Health and Human Services (HHS) seeks public comment on proposed new guidance which will update and replace the 1962 U.S. Public Health Service Drinking Water Standards related to recommendations for fluoride concentrations in drinking water. The U.S. Public Health Service recommendations for optimal fluoride concentrations were based on ambient air temperature of geographic areas and ranged from 0.7-1.2 mg/L. HHS proposes that community water systems adjust the amount of fluoride to 0.7 mg/L to achieve an optimal fluoride level. For the purpose of this guidance, the optimal concentration of fluoride in drinking water is that concentration that provides the best balance of protection from dental caries while limiting the risk of dental fluorosis. Community water fluoridation is the adjusting and monitoring of fluoride in drinking water to reach the optimal concentration (Truman BI, et al, 2002). This updated guidance is intended to apply to community water systems that are currently fluoridating or will initiate fluoridation.\1\ This guidance is based on several considerations that include: --------------------------------------------------------------------------
