Displaced and thinning tmj disc, deep bite

Hi All, I went to see maxfax regarding my deep bite as it was affecting my breathing and speech. I feel that I have less space in my mouth for tongue movement. Maxfax confirmed class 2 deep bite and then asked dentist to refer me to ortho. I also have various tmj symptoms including clicking, popping, ringing ear, constant headache on forehead. I think my lower jaw is shorter….when i push it forward it instantly eases the tension. I’ve had a MRI and they confirmed that my tmj disc on the left is thinning and right disc is displaced.

I’ve had braces in the past and my teeth as almost straight im concerned that ortho will dismiss it, dentist said if you’re not having sleep apnea its unlikely to be reducing airway space. But when i push my jaw forward or wear mouth guard it immediately feels better and breathing is a lot clearer. I have been referred to ortho but im concerned that they’ll have the same view as my dentist :/

is the deep bite fixable using braces? Is it possible that the tmj is caused by deep bite? Also for tmj disc issues maxfax suggested physio - is this normal?
