The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
The debate about the benefits and risks of fluoride is ongoing, as RFK Jr. — incoming President Trump’s pick for HHS secretary — pushes to remove it from the U.S. water supply.
Fluoride's adverse effects depend on total fluoride dosage from all sources. At the commonly recommended dosage, the only clear adverse effect is dental fluorosis , which can alter the appearance of children's teeth during tooth development ; this is mostly mild and is unlikely to represent any real effect on aesthetic appearance or on public ...
Elevated prenatal exposure to fluoride was associated with increased risk of neurobehavioral problems in 3-year-olds, according to a study of children in Los Angeles.
After fluoride was added in many places to the U.S. water supply, tooth decay declined in both children and adults, and complete tooth loss in older adults became more rare, according to federal ...
Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States, fluoride concentrations in water are much higher than normal, mostly from natural sources. In 1986, EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter (mg/L).
In a landmark case, Fluoride Action Network and other health advocacy groups successfully argued that fluoride levels currently promoted as “optimal” by the EPA and other government agencies pose a significant threat to public health, particularly to the cognitive development of children. The United States District Court for the Northern ...
