Fluoridation became an official policy of the U.S. Public Health Service by 1951, and by 1960 water fluoridation had become widely used in the U.S., reaching about 50 million people. [2] By 2006, 69.2% of the U.S. population on public water systems were receiving fluoridated water, amounting to 61.5% of the total U.S. population. [ 3 ]
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay, and is handled differently by countries across the world. [2]Water fluoridation is considered very common in the United States, Canada, Ireland, Chile and Australia where over 50% of the population drinks fluoridated water.
Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States, fluoride concentrations in water are much higher than normal, mostly from natural sources. In 1986, EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter (mg/L).
The U.S. Public Health Service’s recommendation is a fluoride concentration of 0.7 mg/L of drinking water—and there were not enough data to determine if 0.7 mg/L of fluoride exposure in ...
Since 2010, more than 150 towns or counties throughout the country have voted to keep fluoride out of public water systems or to stop adding it, according to the Fluoride Action Network, an anti ...
The report said that about 0.6% of the U.S. population — about 1.9 million people — are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher.
Public water fluoridation was first practiced in 1945, in the U.S. As of 2015, about 25 countries have supplemental water fluoridation to varying degrees, and 11 of them have more than 50% of their population drinking fluoridated water.
In 2022, notes the CDC, more than 209 million people, or 72.3% of the U.S. population served by public water supplies, had access to water with fluoride levels that prevent tooth decay.
