Mouth Ulcer Treatment

The goal of treatment is to relieve symptoms. The cause, if known, should be treated. Gentle, thorough oral hygiene may relieve some of the symptoms. Topical (rubbed on) antihistamines, antacids, corticosteroids, or other soothing preparations may be recommended for applying directly to the ulcer. Avoid hot or spicy foods, which often increase the pain of mouth ulcers.
