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 ...
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 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 ...

In any case, it is only the fluoride that is directly present in the mouth (topical treatment) that prevents cavities; fluoride ions that are swallowed do not benefit the teeth. [ 3 ] Water fluoridation is the controlled addition of fluoride to a public water supply in an effort to reduce tooth decay in people who drink the water. [ 4 ]
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]
