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. Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult ...
The World Health Organization, looking at global public health, identifies fluoride as one of a few chemicals for which the contribution from drinking-water to overall intake is an important factor in preventing disease. This is because there is clear evidence that optimal concentrations of fluoride provide protection against cavities, both in ...
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. 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.
A federal judge in California is considering whether health officials should stop adding fluoride to drinking water. There have been more than 100 lawsuits over the years trying to get rid of ...
Acute fluoride toxicity is possible if someone consumes five liters of fluoridated water at 1 mg/L per every kilogram of body weight, according to the ADA’s fluoridation fact sheet. For example ...
The CDC recommends water fluoridation at a level of 0.7–1.2 mg/L, depending on climate. The CDC also advises parents to monitor use of fluoride toothpaste, and use of water with fluoride concentrations above 2 mg/L, in children up to age 8. [30] There is a CDC database for researching the water fluoridation status of neighborhood water. [31]

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. Sodium fluoride(NaF) was the first compound used and is the reference standard.[35]
