Canker sores are annoying and painful. They are among the most common mouth sores.
What exactly are canker sores? They are small ulcers with a white or gray base and a red border. They appear inside the mouth and are not contagious. There may be only one canker sore or several and they can return frequently.
What causes them? Their exact cause is uncertain but some experts believe that immune system problems, bacteria or viruses may be involved.
Fatigue, stress or allergies can increase the likelihood of a canker sore. Some women may be more prone to them in their premenstrual cycle. A cut caused by biting the cheek or tongue, or reactions from hot foods or beverages may contribute to canker sore development. Intestinal problems, such as ulcerative colitis and Crohn’s disease, also seem to make some people more susceptible.
How do you treat them? Canker sores usually heal on their own after a week or two. Over-the-counter topical anesthetics and antimicrobial mouthrinses may provide temporary relief. Stay away from hot, spicy or acidic foods that can irritate the sore. See your dentist if the sores do not heal after two weeks.
