ADA's dietary fluoride supplement guidelines unchanged after new U.S. fluoride rule

The ADA's dietary fluoride supplement recommendations remain unchanged in light of the new guidelines for community water fluoridation in the U.S., the Association said in a statement in May.

The Department of Health and Human Services released on April 27 the U.S. Public Health Service recommendation for fluoride levels in drinking water for the prevention of dental caries, which is newly calibrated at 0.7 milligrams of fluoride per liter of water from what was a recommended optimal range.

The new recommendation, which was supported by the ADA, does not change the ADA Council on Scientific Affairs' systematic review and clinical recommendation for the use of dietary fluoride supplements that was released in 2010.

Dietary fluoride supplements prescribed by the dentist or physician are based on an individual risk assessment, which includes caries status and child age. The dosage schedule is based on fluoride levels in drinking water as well as other sources of fluoride exposure, including fluoride toothpaste.

In response to the April 27 recommendation, the ADA released a statement applauding the U.S. Public Health Service modiciation and urging communities that are already fluoridating water to continue to do so at the level the government recommends.

"Dentistry is proud of its record in preventing disease," said ADA President Maxine Feinberg in the ADA statement responding to the recommendation. "The ADA and other science-based health organizations in the U.S. and around the world understand that community water fluoridation is one of the most effective and least costly ways to do so."

The Association's eight Action for Dental Health initiatives include extending the availability of optimally fluoridated water. State dental societies and the ADA have a set goal to bring fluoridated water to 80 percent of the population served by public water systems by 2020, using a baseline level of 74 percent in 2010.
