For more than 70 years, community water fluoridation has been scientifically proven to reduce dental caries and improve the quality of life for adults and children across the United States. Fluoridation is the process of adjusting the amount of fluoride naturally found in water to a level known to reduce tooth decay and promote good oral health. All water contains some level of the mineral known as fluoride; however, most natural sources are too low to have any impact on the prevention of cavities. By adjusting the amount of fluoride in drinking water to an optimal level, community water fluoridation has been shown to prevent cavities and save money both for families and the health care system.

The science and research behind community water fluoridation has proven that it is both safe and effective. As a result, the number of people who continue to benefit from this standard oral health practice has grown to more than 75% of the U.S population. Community water fluoridation is supported by the American Dental Association, American Academy of Pediatrics, US Public Health Service, World Health Organization, and the Center for Disease Control. With all the benefits of community water fluoridation, it is clear why the CDC named it one of the 10 great public health achievements of the 20th century.
