You should make sure your dentist checks your bite to ensure you are not hitting that particular tooth more heavily than the rest. You want to make sure you are wearing an orthodontic retainer. You might also consider the "pinhole surgical technique" to improve the gum recession.Good luck!
There are several ways to correct this problem.Oral Surgeons can move the entire maxilla surgically as part of orthodontic treatment plan.Cranio therapy in conjuction with neuromuscular dentistry may be able to non-surgiclly correct the cant of the maxilla. I would have laughed at...
Judging from your photo alone, your palate is quite narrow and has resulted in crowded front teeth.You make a good candidate for invisalign, some expansion of your upper arch will create space to accomodate for straight front teeth and a fuller smile.Good luck! :)
