Oral mucosal lesions are abnormal changes or growths that appear on the lining of the mouth, including the cheeks, gums, tongue, lips, and floor or roof of the mouth. These lesions can vary in appearance, size, shape, and color, and may present as red or white patches, ulcers, lumps, or areas of discoloration. They can be caused by a variety of factors, including infections, trauma, irritants, allergic reactions, autoimmune conditions, or systemic diseases.
