Water fluoridation is the addition of the chemical fluoride to public water supplies, for the purpose of reducing cavities.
Currently, two-thirds of Americans have fluoridated public water, according to the Centers for Disease Control and Prevention (CDC). Of those served by municipal water systems, the figure climbs to 73.9 percent.
A 2009 study that tracked fluoride exposure in more than 600 children in Iowa found no significant link between fluoride exposure and tooth decay. Another 2007 review in the British Medical Journal stated that “there have been no randomized trials of water fluoridation,” which is currently standard for all drugs.
