However, these values differ greatly among the world's regions: for example, in Sichuan, China the average daily fluoride intake is only 0.1 mg/day in drinking water but 8.9 mg/day in food and 0.7 mg/day directly from the air due to the use of high-fluoride soft coal for cooking and drying foodstuffs indoors.

Water fluoridation, which is the act of adding fluoride to drinking water to reach a recommended level, is designed to help prevent cavities, the ADA explains. The ADA refers to this as a “cost ...
It also advises removal of fluoride from drinking water (defluoridation) where the fluoride content is too high. [29] [30] Legislation around mandatory fluoridation was introduced in 2002, but has been delayed since then pending further research after opposition from water companies, municipalities and the public.

Fluoride is a naturally occurring mineral which is present in trace amounts in soil, plants, water and food, and at optimal levels helps to prevent cavities by keeping teeth strong.
What is fluoride? Fluoride is a natural mineral. It is found in soil, air, food and water sources across the planet, although in different amounts depending on the place, according to the National ...
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 ...
U.S. standards recommend fluoride levels of 0.7 milligrams per liter of water, and the NTP’s conclusion applied to water fluorinated at 1.5 milligrams per liter and above.
Fluoride was known to enhance bone mineral density at the lumbar spine, but it was not effective for vertebral fractures and provoked more nonvertebral fractures. [62] In areas that have naturally occurring high levels of fluoride in groundwater which is used for drinking water, both dental and skeletal fluorosis can be prevalent and severe. [63]
