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]
The effect of water fluoridation on the natural environment has been investigated, and no adverse effects have been established. Issues studied have included fluoride concentrations in groundwater and downstream rivers; lawns, gardens, and plants; consumption of plants grown in fluoridated water; air emissions; and equipment noise.

The only generally accepted adverse effect of fluoride at levels used for water fluoridation is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and usually only an aesthetic concern. Compared to unfluoridated water, fluoridation to 1 mg/L is estimated to cause fluorosis in one ...
The Department of Health and Human Services said the data was "insufficient" to determine whether the current recommended level of 0.7 milligrams of fluoride per liter of water also had an effect ...
Water fluoridation is not mandatory, and while there is a recommended fluoride concentration in drinking water (0.7 milligrams per liter) from the CDC, that level is not an enforceable standard.
According to the Centers for Disease Control and Prevention, 72.3% of the U.S. population in 2022 received fluoride in their community water supply. While water fluoridation is not mandatory, the ...
A 2024 Cochrane review article found that adding fluoride to drinking water may lead to slightly less tooth decay among children, but concluded that the practice’s effects are less dramatic ...
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay.
