Fluoridation does not affect the appearance, taste or smell of drinking water. [ 1 ] Water fluoridation is the addition of fluoride to a public water supply to reduce tooth decay.

The water fluoridation controversy arises from political, ethical, economic, and health considerations regarding the fluoridation of public water supplies.. For deprived groups in both maturing and matured countries, international and national agencies and dental associations across the world support the safety and effectiveness of water fluoridation.

Its use began in the 1940s, following studies of children in a region where water is naturally fluoridated. It is now used widely in public water systems in the United States and some other parts of the world, such that about two-thirds of the U.S. population is exposed to fluoridated water supplies [5] and about 5.7% of people worldwide.

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Fluoride (/ ˈflʊəraɪd, ˈflɔːr -/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F−. (also written [F]−. ), whose salts are typically white or colorless.
Defluoridation is the downward adjustment of the level of fluoride in drinking water. Worldwide, fluoride is one of the most abundant anions present in groundwater. Fluoride is more present in groundwater than surface water mainly due to the leaching of minerals. Groundwater accounts for 98 percent of the earth's potable water. [1]
In the mid Fifties, Waldbott began conducting research in fluoride toxicity, becoming one of the first physicians to warn against what he believed was adverse health effects of water fluoridation, particularly among patients in his allergy practice he considered "hypersensitive" to fluoride.
