As for your classmates, it's hard to say, because:
First, I didn't see the photos of your classmates before and after.
Second, maybe you attach too much importance to this, that is to say, the more you look at it, the more you feel that there is a problem.
Orthodontics is a very complicated treatment process. You are still young. You are only 14 years old after orthodontics. At present, it is still in the growth and development stage. When the braces are removed, you should be able to recover. Don't worry, little classmate. I wish you more and more beautiful.
