I think your best bet is to file as you suggested, just enough to be able to get a bb threading tool in to chase the threads. I doubt the bb will need facing, dent is probably not disturbing the bb face plane. The slight loss of full depth threads in that spot won't be a significant mechanical problem. I would not try to bend the bb from the inside or outside, only bad things will happen. IMO for all that.
