There’s something in the water… it’s fluorine!

There’s nothing strong, shiny teeth like more than a tall glass of fluoride. Generated by DALL-E.

Has anyone ever tried to scare you by telling the government is putting something in the water to affect your body? Well it’s true! Fluoride is derived from the element fluorine (Elemingle element #2) and has been added to public drinking water since 1945. Fluoride strengthens teeth and prevents cavities by remineralizing tooth enamel, reversing early tooth decay, slowing down demineralization, and preventing bacterial growth. That's why it is used to fortify drinking water and toothpastes.

The discovery of fluoride is credited to a dentist named Frederick McKay, who was seeking an explanation for brown stains on teeth in 1901. Residents thought these stains might be the result of eating too much pork, consuming inferior milk, or drinking calcium-rich water. Dr. McKay conducted many epidemiological studies and eventually discovered that residents in areas where water had high levels of fluorine exhibited stains - a result of a process called enamel fluorosis. This led to the remarkable discovery that mottled enamel was more resistant to tooth decay, and that adding fluoride to the drinking supply could be a great boon to oral hygiene - but don't worry, the amount added isn't enough to make your teeth brown, or worse, form dangerous hydrofluoric acid. It’s just enough to keep your pearly whites... well, pearly and white!

Fluorine is actually the most reactive element on the periodic table, but synthesized fluoride is much more stable. In addition to making fluoride, fluorine is also used in Teflon, etching glass, and processing nuclear fuel. Pure fluorine is very unstable and hard to store, so you probably won't find it in a beaker in a lab. Humans need minute amounts of it, but in large doses it can be toxic.
