Committee to Coordinate Environmental Health and Related Programs, Ad Hoc Subcommittee on Fluoride (February 1991). Dental fluorosis is a change in the appearance of the dental enamel that occurs in children whose teeth are forming under the gums. The Centers for Disease Control and Prevention (CDC) considers fluoridation of water one of the greatest achievements in public health in the 20th century. Public Health Service, Department of Health and Human Services. Is fluoride a risk factor for bone cancer? In 1993, the Subcommittee on Health Effects of Ingested Fluoride of the National Research Council, part of the National Academy of Sciences, conducted an extensive literature review concerning the association between fluoridated drinking water and increased cancer risk. 2008 Water Fluoridation Statistics. In one of the studies reviewed for the PHS report, scientists at NCI evaluated the relationship between the fluoridation of drinking water and the number of deaths due to cancer in the United States during a 36-year period, and the relationship between water fluoridation and number of new cases of cancer during a 15-year period. Centers for Disease Control and Prevention. The CDC report concluded that studies to date have produced “no credible evidence” of an association between fluoridated drinking water and an increased risk for cancer (2). Many more recent studies have supported this finding (1). However, other studies in humans and in animals have not shown an association between fluoridated water and cancer (5–7). ABOUT. Water fluoridation is the process of adding fluoride to the water supply so the level reaches approximately 0.7 ppm, or 0.7 milligrams of fluoride per liter of water; this is the optimal level for preventing tooth decay (1). After examining more than 2.2 million cancer death records and 125,000 cancer case records in counties using fluoridated water, the researchers found no indication of increased cancer risk associated with fluoridated drinking water (6). Carcinogenicity of fluoride. from 0.7 to 1.2 ppm.

The Environmental Protection Agency has more information about drinking water and health at https://www.epa.gov/ground-water-and-drinking-water. The natural level of fluoride in Wellington’s water is around 0.1 milligrams per litre or parts per million (ppm). When did water fluoridation begin in the United States? drinking water to 1.0 ppm, a level recommended for optimal dental health in our climate. As of 2012, about 435 million people worldwide received water fluoridated at the recommended level (i.e., about 5.4% of the global population). Blakey K, Feltbower RG, Parslow RC, et al. Our syndication services page shows you how. As with other nutrients, fluoride is safe and effective when used and consumed properly. A possible relationship between fluoridated water and cancer risk has been debated for years. This recommendation, released April 27, updates and replaces the previous recommended range (0.7 to 1.2 milligrams per liter) issued in 1962. Why was this determined as the benchmark level? * parts per million, ppm, is equivalent to one cent in $10,000 FREQUENTLY ASKED QUESTIONS Is water fluoridation safe? this is the level at which a substantial reduction in caries was exhibited with an acceptable or inconsequential level of fluorosis.
