How long will i need braces for do you think?

Only an ortho can tell you that. They also look at things you aren't looking at. You're just looking at cosmetics, but they look at how your bite is lined up too. I just needed a few spaces closed up, so I got braces. The spaces closed pretty quickly, but guess what the hold up was? My molars ... which I didn't even have a problem with! My bite wasn't aligning very quickly. That's why I had to continue wearing braces after the spaces closed. Go have an orthodontic consultation.
