60 Years Strong: Fluoridation Celebrates Anniversary

On January 25, 1945, Grand Rapids, Michigan became the first city in the world to adjust the fluoride level in its public water system in an effort to prevent tooth decay. And while often overlooked in history books, undeniably water fluoridation has become a staple in America’s health care system. Today, some 170 million Americans—more than 67%—receive optimal levels of fluoride from their public water supply.

Within the first ten years following the initiation of fluoridation, researchers saw a 60% decrease in dental caries in the primary teeth of children living in Grand Rapids, and a 35% decrease in caries in adults. The research also showed no negative effects from the fluoridation process.

Now on its 60th anniversary, water fluoridation is having a more obvious effect than ever. The Centers for Disease Control and Prevention (CDC) estimate that having access to a fluoridated water supply results in an 18–40% reduction in the incidence of tooth decay.

To help celebrate this monumental occasion, a national fluoride symposium, hosted by the American Dental Association and CDC, will be held in Chicago July 13–16. The event will be open to the public, and oral health care professionals, public health officials, and community leaders are expected to attend. The intent of the symposium will be to improve public health in the United States with a focus on the benefits of water fluoridation.
