I had braces and after the treatment I lost my retainers so I never wore them. My teeth started to move and one got pushed back and is loose because of bone loss. I don’t want to get surgery for it because I already have gotten so many mouth surgeries. One Perio said I could get Invisalign but was sure that once aligned, that tooth would fall. And the second option was getting a splint. Is it possible to get this fixed without surgery? What can I do to make it look normal if I can’t move it ?
