Hi.
I certainly understand your concern?
I would like you to quit chewing tobacco on a priority basis , chewing tobacco can worsen the TMJ function as you're giving it excessive stress when it's already under stress.
You can neither blame Doctors as I'm sure, many Dr whom you visited might have advised to quit chewing habits, treatment will be successful only when you follow all the instructions given by the doctor and depending on how your body responds to the treatment ,and treatment cannot be expected in a short duration.
Kindly Come out of Your Comfort Zone and focus on your goal so that your health is in a good state and function.
Hope your question is answered
Next Steps
Completely Quit chewing and then visit the dental surgeon or ENT for desired results.
Physical examination and evaluation is required.
