And yet I read plenty of horror stories of bad orthodontic results. Ask me how I know.

Went to 3 different orthodontist to fix what a bad orthodontist did to me when I was a kid, and each gave me a completely different treatment plan. I feel like being an orthodontist is just eyeballing and patching your way as you go to an acceptable resolution.

Given that, shouldn't you be even more concerned about people YOLOing it, if even highly trained orthodontists are regularly screwing this up?
