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]
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]
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.
Fluoride monitor (at left) in a community water tower pumphouse, Minnesota, 1987 Fluoridation does not affect the appearance, taste, or smell of drinking water. [1] It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate.
Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]
A federal judge has ordered the U.S. Environmental Protection Agency to further regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.
Defluoridated water from this suggested method provides calcium-enriched alkaline drinking water as generally fluoride contaminated water has a low amount of calcium mineral and drinking alkaline water helps in eliminating the toxic fluoride from the body.
