Oral Submucous Fibrosis causes stiffness of the mouth tissues and restricted tongue movement, and the most important step is to completely stop chewing tobacco, gutkha, or areca nut. Treatment may include medications and supplements (like antioxidants and vitamins), and sometimes doctor-given injections to reduce fibrosis. Regular mouth-opening exercises and physiotherapy are very important to improve movement. In severe cases, surgical treatment may be needed. Regular follow-up with a doctor or dentist is essential, as this condition needs monitoring.
