Five Things You May Not Know About Community Water Fluoridation

Why Fluoridation?

According to the U.S. Centers for Disease Control and Prevention , Americans have been drinking water fortified with fluoride, a naturally occurring mineral, for 70 years.1 While most water has small amounts of this trace element, adding fluoride in the form of sodium fluoride or sodium monofluorophosphate has been shown to be beneficial to dental health.

While you may know that community water fluoridation is generally good for our teeth, here are some things you may not know about public health programs for fluoridated water:

  • Fluoride can stop or even reverse the tooth decay process, keeping tooth enamel strong. It works to remineralize tooth surfaces that have been removed by certain bacteria in the mouth that cause tooth decay, preventing cavities from forming. Fluoride is safe for both children and adults.2
  • While drinking fluoridated water is not a substitute for brushing your teeth and visiting the dentist, it can reduce tooth decay and cavities by about 25% in children and adults.1 As an added benefit, this saves Americans in dental and healthcare costs.
  • Nearly all major public health, medical, and dental organizations recommend community water fluoridation, including the American Dental Association, the American Academy of Pediatrics, and the World Health Organization.
  • More than 66% of the U.S. population receives fluoridated community water, but some states have much higher rates of fluoridation than others. The District of Columbia, Georgia, Illinois, Kentucky, Maryland, Minnesota, North Dakota, and Virginia have some of the highest rates of people receiving fluoridated community water. Hawaii, Idaho, Louisiana, Montana, New Jersey, and Oregon have some of the lowest rates.3
  • The CDC has placed community water fluoridation on its list of the 10 great public health achievements of the 20th century for its contribution to the large decline in cavities in the U.S.4
