The fact that anyone was ever convinced that drinking fluoride prevents cavaties is fucking sad. The logic is akin to applying sunscreen while showering, or taking vitamins at the same time as a laxative. And that's of course totally besides the fact that fluoride does very bad things once it gets absorbed into your blood.

Your daily reminder to megadose Iodine every few days. It displaces Fluorine ions in your body. Fluoride is also heavily implicated in thyroid diseases
It's out of your bloodstream quickly, less than a day.. but chronic exposure leads to accumulation in your bones, and the half-life in bone is like 20 years.
