There is no specific toothpaste or mouthwash that can cure oral submucous fibrosis (OSF) on its own. For daily care, use a mild, fluoride-containing toothpaste and an alcohol-free mouthwash. Avoid strong mint, menthol, or spicy flavors, as they can irritate your sensitive oral lining. For treatment, a dentist may prescribe a steroid mouthwash containing betamethasone to reduce inflammation and stiffness. The most crucial step is to completely stop chewing areca nut, gutkha, or tobacco. Please consult an oral specialist for a tailored treatment plan, which may include antioxidant supplements and mouth-stretching exercises. With proper care, this condition can be managed effectively.
