I already have braces I've had them for a little over a year and a half. And a yesterday my teeth on the top left of my mouth started hurting really bad. I looked in the mirror and my left front tooth is starting to overlap the right and a the tooth to the left of my left front is going under it and the one to the left of that is overlapping that one. It's really really painful. Is this normal? Or should I go see my orthodontist?
