These symptoms suggest a manageable condition called Oral Submucous Fibrosis, often linked to habits like chewing betel nut or tobacco. The most crucial first step is completely stopping these habits. To improve your mouth opening and ease the burning sensation, doctors typically prescribe: Antioxidants: Generic lycopene, beta-carotene, and vitamins (A, C, and E) to help heal the mouth lining. Corticosteroids: Topical triamcinolone paste or local dexamethasone injections to reduce tissue stiffness and inflammation. Enzymes: Hyaluronidase injections to help soften fibrous bands. Vasodilators: Pentoxifylline tablets to improve local blood flow. Please consult a dentist or oral specialist for a personalized prescription and guided mouth-opening exercises.
