National Institutes of Health, Fluoride Fact Sheet, Updated June 26, 2024. U.S. Centers for Disease Control and Prevention, Community Water Fluoridation Frequently Asked Questions, May 15, 2024.
The U.S. Public Health Service recommends a fluoride concentration of 0.7 mg/L of drinking water. NIH's Taylor said there was not enough data to determine whether that level has any impact on ...
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 is considered a semi-essential element for humans: not necessary to sustain life, but contributing (within narrow limits of daily intake) to dental health and bone strength. Daily requirements for fluorine in humans vary with age and sex, ranging from 0.01 mg in infants below 6 months to 4 mg in adult males, with an upper tolerable ...
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).
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]
Since 2015, the Public Health Service has pegged the "optimal" concentration of fluoride at 0.7 mg/L, the equivalent of about 3 drops of fluoride in a 55-gallon barrel. (Prior to that, the target ...
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.
