My midline is shifted to one side after braces treatment. How to correct it?

Hello doctor,

I have this issue where my midline is shifted. It is not centered as it should be, and like the whole arch (mandibular and maxillary) is shifted as if you just pulled it from one side. It shows in the picture, especially with the back camera, which made me insecure about myself. I am wearing braces, and I have been wearing them for a year and a half now. My orthodontist removed the lower braces and is willing to remove the upper one in the next appointment. Although I told him about my problems, he says that it is not that much, but your age pictures show the opposite. What are the treatment in my case like? Can it be treated with elastics or what? I have pictures of my teeth.
