Fluoridated water is one of the most efficient and effective ways to deliver fluoride.
In fact, the U.S. Centers for Disease Control and Prevention believe that fluoridating community water is one of the 10 greatest public health achievements of the 20th century. More than 65 leading health organizations, including the American Dental Association (ADA), Massachusetts Dental Society, American Academy of Pediatric Dentistry, American Medical Association, World Health Organization, and American Cancer Society, advocate for community water fluoridation on the basis of the scientific evidence that continues to support its safety and effectiveness.
What is Community Water Fluoridation?
Community water fluoridation (CWF) is the adjustment of sub-optimally fluoridated water levels up to the levels recommended for optimal dental health. The U.S. Department of Health and Human Services (HHS) recommends the optimal fluoride concentration level of 0.7 parts per million (ppm).
One milligram per liter (mg/L) of fluoride in water equals one part per million (ppm). One ppm of fluoride is diluted in a million parts of water. The following comparisons give an idea of the amount of one part per million: 1 inch in 16 miles; 1 minute on 2 years; 1 cent in $10,000.
At this concentration level, dental decay is effectively reduced while minimizing the risks of dental fluorosis. The optimal level for a location depends on the annual average maximum daily air temperature of the geographic area.
There are three types of additive options approved by the American Water Works Association and NSF International: sodium fluoride, sodium fluorosilicate, and fluorosilic acid. The benefits of community water fluoridation are the same regardless of the source.
