It’s kids so cut them some slack ….

I wonder what those dental hygiene stats look like

no doy. the story of how it came to be in our water is kinda cool and sciencey dentists were like hey why are these people near colorado springs not getting as many cavities but also have kinda brown stained teeth, and discovered there was high levels of fluoride in the water naturally (still safe for health) and people did some science to make it lower so it didn't stain teeth but provided teeth protection,  so it's not some foreign substance that we add out of nowhere it's a natural occurrence in some places that was beneficial so we borrow it and put it the other water

Fluoride is very effective.  Iodine in salt, too
