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.

Water fluoridation reduces cavities in children, while efficacy in adults is less clear. [9] [10] [11] A Cochrane review estimates that when water fluoridation is used by children who have no other access to sources of fluoride, there is a reduction in cavities by 35% in baby teeth and 26% in permanent teeth. [9]
A book review of Waldbott's book Fluoridation: The Great Dilemma in the journal New Scientist closes with this statement "Laymen, including those concerned with decisions on fluoridation, will be impressed by what seems to be the reasonableness of the case, oblivious to the omissions and obsolete presuppositions upon which much of it is based."
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. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. [ 2 ]
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]
The benefits of water fluoridation have lessened recently, presumably because of the availability of fluoride in other forms, but are still measurable, particularly for low-income groups. [9] Systematic reviews in 2000 and 2007 showed significant reduction of cavities in children exposed to water fluoridation. [10]
