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.
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]
In fact, 75% of fluoride intake comes from drinking water with added fluoride and from food and beverages, such as sodas and fruit juice, made with fluoridated water, according to the CDC.
Soluble fluorides are moderately toxic. For sodium fluoride, the lethal dose for adults is 5–10 g, which is equivalent to 32–64 mg of elemental fluoride per kilogram of body weight. [68] The dose that may lead to adverse health effects is about one fifth of the lethal dose. [69]
Water fluoridation, which is the act of adding fluoride to drinking water to reach a recommended level, is designed to help prevent cavities, the ADA explains. The ADA refers to this as a “cost ...
Fluoride – it's added to the water systems of more than two thirds of Americans. It's in dental products from toothpaste to mouth wash. It's been the subject of long-running conspiracy theories.
Soluble fluorides are moderately toxic: 5–10 g sodium fluoride, or 32–64 mg fluoride ions per kilogram of body mass, represents a lethal dose for adults. [273] One-fifth of the lethal dose can cause adverse health effects, [ 274 ] and chronic excess consumption may lead to skeletal fluorosis , which affects millions in Asia and Africa, and ...
The well known toxicity of these esters led to fears that the simple salts might also be toxic, and such fears precluded any large scale commercial use of the salts. In 1950, under sponsorship of the manufacturer of the compounds, Ozark Chemical Company , the toxicity of sodium monofluorophosphate was studied by Harold Hodge at the University ...
