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.
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.
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 lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride per kg body weight).
Chronic fluoride toxicity would only develop after 10 or more years of consuming levels of fluoridated water much higher than the recommended 0.7 mh/L. Skeletal fluorosis, a bone disease that ...
What will happen if fluoride is removed from water in the U.S.? If community water fluoridation is ended in the U.S., the biggest and most immediate impact will be seen in an increase in dental ...
The clinical symptoms of fluoride toxicity in the bones are indistinguishable from arthritis. Even low level exposure to fluoride can cause or worsen the symptoms in consumers with vulnerable genotypes. [5] [6] [7]
Fluoride is a naturally occurring mineral which is present in trace amounts in soil, plants, water and food, and at optimal levels helps to prevent cavities by keeping teeth strong.
Fears about fluoride were likely exacerbated by the reputation of fluoride compounds as insect poisons and by early literature which tended to use terms such as "toxic" and "low grade chronic fluoride poisoning" to describe mottling from consumption of 6 mg/L of fluoride prior to tooth eruption, a level of consumption not expected to occur ...
