I am 23 years old boy.My mouth does not open completely since my childhood,It is restricted upto 2 fingers or 25 mm.I never ate tobacco in my life.There is no history of tobacco consumption I have also got crossbite in my teeths.I went to a local dentist,he told me that I have tmj ankylosis in right side.My right side of the mouth is little bit restricted. But due to Covid I never visited him again. I can't open my mouth beyond 25 mm and I feel tightness when I try to open it. Does it require any surgery or it can be opened by conservative methods??
