[|Human|] i m unable to open my mouth properly due to chewing tobaco from last 5 years. i gave up my habit since last 3 months. i am also feeling uncomfortable while eating. i can enter only 2 fingers in my mouth.Please tell me how can i overcome this.     Thanking youkishore
[|AI|]  Chewing tobacco can cause reduced mouth opening (Erasmus) by two effects:1. Oral submucosal fibrosis in which tissue in layer beneath the lining (mucosa) of mouth (oral cavity) gets fibrosis (fixed and hardened due to changes). Although it is a benign condition, but it is quite troublesome as patient cannot open mouth adequately resulting in difficulty eating and speaking.2. Oral cancer which has advanced locally to involve muscles, muscle spaces or joints of mastication (chewing) which are also responsible for mouth opening. In both cases you need to see your dental surgeon who after examination will advise biopsy and CT scan imaging from base of skull to root of neck to get to an exact diagnosis. I hope it helps. Please discuss it with your doctor.
