What should I do if a mouth ulcer doesn't heal for a month?

If a mouth ulcer does not heal within a month, comprehensive measures should be taken: 1. Adjust dietary habits to avoid spicy and irritating foods. Eat more fruits and vegetables rich in vitamins, such as apples and celery. 2. Local medications can be applied, such as Bingpeng Powder (Ice Boron Powder) or oral ulcer powder, to relieve pain and promote healing of the oral mucosa. 3. If symptoms persist, consider systemic treatment, such as supplementing with vitamin C and B-complex vitamins, or using glucocorticoids as directed by a physician. 4. Physical therapies such as laser or microwave therapy can also aid in ulcer healing. If a malignant oral ulcer is suspected, seek timely medical evaluation for pathological examination and, if necessary, undergo surgical treatment. Additionally, maintain good oral hygiene, follow a regular作息 schedule, enhance overall immunity, and promote faster recovery from ulcers.
