Fluoride toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Although fluoride is safe for dental health at low concentrations, [ 1 ] sustained consumption of large amounts of soluble fluoride salts is dangerous.
All fluoridation methods, including water fluoridation, create low levels of fluoride ions in saliva and plaque fluid, thus exerting a topical or surface effect. A person living in an area with fluoridated water may experience rises of fluoride concentration in saliva to about 0.04 mg/L several times during a day. [3]

How much fluoride is the right amount? Today, over 72 percent of the U.S. population on community water systems receives fluoridated water, according to the CDC. But adding fluoride to public ...
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 ...
Water and food sources of fluoride include community water fluoridation, seafood, tea, and gelatin. [52] Soluble fluoride salts, of which sodium fluoride is the most common, are toxic, and have resulted in both accidental and self-inflicted deaths from acute poisoning. [4]
The ADA notes that you would have to drink five liters of water for every kilogram of body weight at once to have fluoride toxicity — which is a toxic amount of water.
