Well my teeth roots aren't showing, but if you're an adult and get ortho, you're going to lose papilla and maybe bone. They don't tell you that. It's criminal.
This is probably true in most cases, yes. Thinking pessimistically, if even a third of their adult patients end up with good results (aka not enough visible bone loss), they have plenty of ideal results to show off. This is how I think now haha - I'm just waiting for a paradigm shift in treatment options, because the current stuff makes me sick!
On the bright side, tech companies like Google have a huge surplus of unspent earnings every year that they can dump into Biotech/AI - so those things are next on the list.
