I’m 41 years old.  I don’t recall that when I was 13 or 14 the first time around with braces, I was this uncomfortable.
The orthodontist assistant who clipped the teeny tiny bit of wire that was ravaging my inner cheek (again) said that adults patients are a pain. She said it nicely, of course. I’m not surprised. We don’t heal as quickly.
