TMJ disorder. This medical condition.

I got inflammation in my jaw joints. Initially it started with right side then progresses to left side in 3.5 months, I'm on regular medication but no relief. Right side TMJ joint is detected  hypermobile & slight dislocation on opening of mouth. However, dislocation is not confirmed yet as more clinical findings are required to conclude. I've consulted multiple docs including ENT & dental surgeon, some prescribed joint injection, some suggested orthodontic treatment(braces), surgeries etc. I'm feeling really hopeless as I'm unable to recover from it. It's painful medical condition impacting my daily routine like difficult to eat, laugh, speak. I'm in need of some permanent solution which can cure the root cause, not a temporary relief. Could you please suggest the exact treatment required to fix this medical condition.
