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.
