Oral submucous fibrosis is an
oral potentially malignant disorder. In a tobacco/areca-nut chewer, an ulcer could be traumatic or inflammatory, but it also needs exclusion of epithelial dysplasia or oral squamous-cell carcinoma. Arrange
urgent oral medicine, oral and maxillofacial surgery, ENT, or dental oncology assessment, particularly if the ulcer has lasted
more than 2 weeks, is indurated, non-healing, red-white, bleeds, has raised/everted edges, causes numbness, neck nodes, weight loss, or reduced mouth opening. A biopsy is the definitive diagnostic step for a suspicious oral lesion, as noted in the
ADA early-detection guideline.
Do
not assume that “inflammation” makes it benign, and do not delay referral while trying multiple topical medications. Oral submucous fibrosis can cause progressive restricted opening and has malignant potential, particularly with continued areca/tobacco exposure. Current evidence supports habit cessation as the mainstay; drug approaches have limited and generally low-certainty benefit. The 2024
Cochrane review found only modest, uncertain benefits for several interventions, so specialist-directed treatment is preferable.
