Oral white spot ulcers are healed, the red side of the center is still white, consider the persistence of oral mucosal white spots. 1. Oral mucosal leukoplakia generally does not have complications or permanent damage, eliminating the stimulus after a period of pain will be relieved, the ulcers will also improve with time. However, the white spots themselves may persist, and there are no specific drugs that can treat them. 2. Oral mucosal leukoplakia is a white plaque that occurs in the oral mucosa, mostly in men, and is closely related to long-term inflammatory stimuli, such as alcohol, tobacco, etc., as well as systemic nutrient deficiencies. 3. Most of the patients have no conscious symptoms, occasionally found when checking the oral cavity. Some patients may have localized roughness, numbness and astringency. The affected area is harder than the surrounding mucosa when stroked, and there will be pain when there is ulcer or cancer. The prognosis of this disease is good, and there is a 3% to 5% chance that mucosal white spots will become cancerous. Even if the white spots are eliminated, the patient’s risk of oral cancer is still higher than that of the general population, so regular medical checkups are needed.
