The new recommendation will help ensure an effective level of fluoride to reduce the incidence of tooth decay, while minimizing the risk of cosmetic fluorosis in the general population.
ADA Applauds USPHS Final Recommendation on Optimal Fluoride Level in Drinking Water

The Association strongly urges communities that already are doing so to continue fluoridating water at the levels the government recommends. People who live in the dwindling number of non-fluoridated communities should help educate their state and local officials about the need to fluoridate. They also should talk to their dentists about other ways to ensure that they are receiving the right amount of fluoride, through such means as supplements or topical applications.
“Dentistry is proud of its record in preventing disease,” said Dr. Feinberg. “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 recommended level is now officially set at 0.7 parts per million, but the health benefits have not changed, and neither has the ADA’s commitment to bringing optimally fluoridated water to the greatest possible number of people.”
