Been hearing that for decades now. I'll believe it when I can access it.

i have dental connections. what i understand is there are two different things to watch. there's a treatment that might be able to get your own body to grow another (final) set of teeth. theoretically humans can grow 3 sets, we stop at the second. that's in the works, sounds pretty painful. the other treatment is something that can regrow dentin or enamel or i can't remember it's been a while, but the one they'd be excited about is enamel so it's probably that? IIRC they both were coming out of South Korea, one in phase 1 trials and one still in animal trials.

this is me trying to remember off a conversation with my deceased dad's friend a couple months ago, so take it with a heaping heap of heaps of salt. my memory ain't all that great anymore.
