Another question about TMJ.?

I am developing TMJ due to a poor bite and bruxism. I already wear a night-time splint. My dentist wants to refer me to an orthodontist for braces and what ever else needs to be done to fix my bite. I am 28, my dental insurance does not cover ortho for anyone over 18. I have had some work done, 2 root canals+crowns, fillings, but they say I have solid bone structure and could fix my bite. It will cost alot of $$$ do you think it is worth it?
