hi there
thanx for the query
first of all your condition is OSMF, which requires cessation of pan gutka absolutely. you need to get your treatment started with your medication and surgical treatment by an oral surgeon as soon as possible.(your condition requires specialist and clinical condition's current status can be only assessed by someone who does your physical examination.)
this condition is quite chronic now so make a positive bent of mind and go ahead with the treatment as soon as possible.
take care
have patience
regards

hello there....you have a condition called Oral submucous fibrosis (OSMF)....Chewing tobacco would cause an irreversible condition known as Oral submucous fibrosis (OSMF)....muscles underneath your cheek gets rigid and looses its elastic property... we call that fibrosis...Once the elasticity of the muscles are lost you would loose the ability to open mouth... Continuos chewing of tobacco would result in depletion of glycogen to the muscles...the muscle becomes fatigue....blood supply decreases...As this happens your muscles tend to get more fibrosed. Based upon the severity, in terms of mouth opening, the management plan differs...This has nothing to do with the TM joint
If you are unable to open more than 1 finger space then you are a candidate for surgery... You are bound to get very good results with regular mouth opening if operated properly...Get your evaluated and examined by a Oral and Maxillofacilal Surgeon only...These specialists are experts in managing these conditions...Medication wont improve...Get yourself evaluated...
