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.
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 ...
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. ... Young children inadvertently swallow ...
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).
In many industrialized countries swallowed toothpaste is the main source of fluoride exposure in unfluoridated communities. [61] Other sources include dental products other than toothpaste; air pollution from fluoride-containing coal or from phosphate fertilizers; trona , used to tenderize meat in Tanzania ; and tea leaves, particularly the tea ...
A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children. The report, based on an analysis of ...
In any case, it is only the fluoride that is directly present in the mouth (topical treatment) that prevents cavities; fluoride ions that are swallowed do not benefit the teeth. [3] Water fluoridation is the controlled addition of fluoride to a public water supply in an effort to reduce tooth decay in people who drink the water. [4]
In August, a federal report found that high levels of fluoride in drinking water (i.e., at twice the currently recommended limit) is linked to lower IQ in children.
