Hello, mouth opening can be restricted because of two reasons-first the soft tissue (muscular or mucosa, etc) part, second the hard tissues (bones) related to Temporomandibular joint/ jaw joint. In India, Oral Submucous fibrosis is the commonest due to Gurkha, sugar, spicy food chewing habits., it is characterized by loss of elasticity of cheek mucosa which hampers oral opening. Its treatment involves injections in cheek mucosa and sometimes surgery along with oral physiotherapy- forceful opening of mouth by certain exercises after medicines.some muscular spasm also restricts opening, but they are resolved as soon as muscles relaxes by medicines and do not persist for long period like 3 months mostly. Regarding temporomandibular joint-the problem in the articular space by its fibrosis due to trauma, autoimmune diseases of joints-arthrosis, arthritis,etc. can cause restricted oral opening. For it the injections are given in joint spaces to resolve fibrosis. And if it doesn't help then surgery is advised which is slight complicated. So if the joint space responds to injectable treatments the surgery is avoided. Though it takes time, but problem will resolve later on.a proper clinical evaluation supported with few radiographs including OPG, TMJ view (open and closed), MRI of joint etc. Will help in reaching the correct diagnosis. U can consult an oral medicine and diagnosis specialist along with an oral surgeon for treatment.Meanwhile, maintain oral hygiene. And follow all the instructions exercises advised by the docs treating him.take care
