Opposition to water fluoridation
Opposition to water fluoridation refers to activism against the fluoridation of public water supplies. The controversy occurs mainly in English-speaking countries, as Continental Europe does not practice water fluoridation, although some continental countries fluoridate salt.[1] Most of the health effects are associated with water fluoridation at levels above the recommended concentration of 0.7 – 1.2 mg/L (0.7 for hot climate, 1.2 in cool climates), but those organizations and individuals opposed raise concerns that the intake is not easily controlled, and that children, small individuals, and others may be more susceptible to health problems. Those opposed also argue that water fluoridation is ineffective,[2] may cause serious health problems,[3][4][5] and imposes ethical issues.[6] Opposition to fluoridation has existed since its initiation in the 1940s.
