Quite often when orthodontics can help with TMJ is when the teeth have become worn down. Orthodontics can "verticalize" teeth (raise lower teeth up and upper teeth down). This gets the nose and chin at the right distance (if they get too close together, the joint gets strained).
This is assuming braces can help, and sometimes it can. Invisalign has a challenging time verticalizing teeth (if often can't).
The first step in helping your TMJ situation is getting a proper diagnosis and resolution of pain. From THAT point, you can determine if braces can help.
