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 authors also noted that adding fluoride to drinking water may increase the number of people with dental fluorosis, a mostly cosmetic condition that can leave the teeth with white flecks, spots ...
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.
WHO states that long-term exposure to fluoride levels above 1.5 milligrams per liter (mg/L) in drinking water can lead to health problems. Does water fluoridation help? Evidence is mixed
Many people do not know that fluoridation is meant to prevent tooth decay, or that natural or bottled water can contain fluoride. As fluoridation does not appear to be an important issue for the general public in the U.S., the debate may reflect an argument between two relatively small lobbies for and against fluoridation. [72]
Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are ...
That doesn't mean the water is fluoride-free: According to the Los Angeles Department of Water and Power, the city's groundwater contains fluoride at concentrations ranging from 0.1 to 0.3 mg/L ...
Fluoride – it's added to the water systems of more than two thirds of Americans. It's in dental products from toothpaste to mouth wash. It's been the subject of long-running conspiracy theories.
