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.
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 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.
In the mid Fifties, Waldbott began conducting research in fluoride toxicity, becoming one of the first physicians to warn against what he believed was adverse health effects of water fluoridation, particularly among patients in his allergy practice he considered "hypersensitive" to fluoride. [8]
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.
Toxic fluoride and cyanide compounds that are leachable in water; Corrosive - exhibiting high pH due to alkali metals and oxides; Reactive with water - producing inflammable, toxic and explosive gases. [2] The toxic, corrosive and reactive nature of SPL means that particular care must be taken in its handling, transportation and storage. [2]
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.
