Implementation of new recommendation for fluoride concentration in drinking water for prevention of dental caries

Community water fluoridation has been recognized as one of ten great public health achievements of the 20th century and as a major contributor to improved oral health for the American public. 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. The U.S. Department of Health and Human Services (HHS) in January 2011 issued proposed recommendations to change the recommended optimal amount of fluoride in drinking water from a level ranging from 0.7 to 1.2 mg/L based on ambient air temperature to a uniform amount of 0.7 mg/L. HHS convened a Federal inter-departmental, inter-agency panel of scientists to review scientific evidence related to recommendations for fluoride concentrations in drinking water in the U. S. The rationale for the change in optimum and the process followed in finalizing the recommendation will be reviewed. Issues regarding implementation of the final recommendation will be presented. Implementation may raise issues regarding water system administration, communication with the public, and adjustments to state and local administrative rules, law, regulation, or ordinance.
