> There are suspicions that fouride isn't good for us, and I mean beyond our precious bodily essences too, but in terms of teeth, it's been miraculous.

Fluoride is weird. Everyone just assumes some is good so more must be better, and any research into dental fluorosis (over exposure) is shunned. I believe primarily because prior to dumping it into the water and every dental product imaginable fluoride was expensive to dispose of and we produce a ton of it as a byproduct of making fertilizer.

too much flouride is actually really bad for your teeth; brown spots/pits I think. It's why children's toothpaste has minimal flouride, because they swallow a lot of it.

adults: don't swallow your toothpaste.

i had white spots (Dental Fluorosis) as a kid from too much flouride... they eventually went away.

White spots is mild fluorosis. The brown stuff comes in when you live next to a coal mine so your water is filled with fluoride (at concentrations way over what any reasonable water-fluoridizer wants to add) and other nasty stuff.

People talk about how the fluoride in tea can help prevent cavities, but on the darker side... just imagine having all your food come from that sort of fluoride-rich soil.

It always amazes me how awful and toxic the earth can be once you get below the surface that's been rinsed with rain, biological acids, and otherwise weathered and covered up with thoroughly processed particles for millions of years.

I was curious as to where the fluoride was coming from, and this report: https://sci-hub.ee/https://link.springer.com/article/10.1007... seems to indicate that the mines increase fluoride in grounderwater due to exposing carbonates which then can dissolve, kicking off a change in pH and various other reactions that release fluoride from the minerals it's otherwise locked in.
