Options for widening lower dental arch?

I had a consultation with an oral surgeon today and they said I would probably have to have extractions before corrective jaw surgery because of crowding. I meet with an orthodontist next month, but I'm getting kind of anxious and would like a second opinion now. Is it possible to widen my lower dental arch without extractions, maybe tipping? Or is my lower jaw too narrow? I should mention, none of my wisdom teeth came in, they all had to be surgically removed.
