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 humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight).
Robert F. Kennedy Jr. says fluoride should be removed from drinking water, but experts say the naturally occurring mineral is safe and improves oral health
The U.S. Public Health Service’s recommendation is a fluoride concentration of 0.7 mg/L of drinking water—and there were not enough data to determine if 0.7 mg/L of fluoride exposure in ...
The Department of Health and Human Services said the data was "insufficient" to determine whether the current recommended level of 0.7 milligrams of fluoride per liter of water also had an effect ...
Fluorine, in the form of fluoride, is considered to be a micronutrient for human health, necessary to prevent dental cavities, and to promote healthy bone growth. [28] The tea plant ( Camellia sinensis L.) is a known accumulator of fluorine compounds, released upon forming infusions such as the common beverage.
Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to determine the human body's capacity for ridding itself of fluoride. [69 ...
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 ...
Fluoride's effects depend on the total daily intake of fluoride from all sources. Drinking water is typically the largest source; [19] other methods of fluoride therapy include fluoridation of toothpaste, salt, and milk. [20] The views on the most efficient method for community prevention of tooth decay are mixed.
