yeh i think just was exposed to too many different sources and they stacked.

the issue is it forms layers through ur calcium deposits as you are growing, so like the idea is that you regulary are getting an even, constant, little amount that is dispersed through ur bones and teeth as u grow, but at some stages I had massive exposures and the flurine formed thicker layers in pockets that are harder but more brittle, and so these pockets crack. my teeth kinda lose flakes of these thick white flurine layers over years like a croissant kinda flaking off
