How to correct a midline with missing right lateral incisor? (Photo)

I'm missing my right lateral incisor, my teeth have shifted to the right and as a result my midline is off. I also have small gaps in between a few of my teeth, the biggest between my central incisor and my right canine. I went in to the dentist to see if veneers or something similar could correct the problem but he said I needed to correct the midline first. What treatment options do I have and about how long would it take? Thanks
