Oral leukoplakia is a precancerous condition characterized by white or grayish patches or lesions on the oral mucosa. The exact cause of this condition is unknown, but it is associated with harmful habits such as smoking, alcohol consumption, and betel nut chewing. Oral leukoplakia can occur anywhere in the mouth, most commonly on the gums, the occlusal line of the buccal mucosa, and the tongue. Patients may not experience noticeable symptoms and often discover the condition incidentally. Some patients may feel roughness, numbness, or a stiff sensation in the affected area, which feels harder than the surrounding mucosa. Pain may occur if ulcers or erosions are present. The lesions of oral leukoplakia vary in appearance, including plaque-like, wrinkled paper-like, wart-like, granular, and ulcerated forms. Currently, there is no definitive cure for oral leukoplakia. Management primarily involves regular follow-ups, eliminating local irritants, periodic monitoring, and preventing malignant transformation. Surgical intervention may be necessary in some cases.
