Options for widening lower dental arch?

I agree with the oral surgeon.  In order to get the maximum results, you would need to push back the front teeth as much as possible. Good luck!

First of all you have truly beautiful teeth.  You do have a space problem however.  Room for your existing teeth is often created by removing premolars.  If that is what your orthodontist also recommends I would not worry very much about the procedure.  There will be no significant pain and you teeth will look amazing.  Good luck!
