How to fix lateral incisor length discrepancy caused by braces? (photos)

I've been wearing braces for 9 months. After shifting my top teeth to far right my orthodontist is now trying to shift them left via to elastic bands (see pic). After wearing them for 2 weeks straight my left lateral incisor has become longer than the right and my bite is still not much better. I could really use some help understanding how to fix this length discrepancy and how to better fix the bite since these elastic bands seem to have made everything worse.
