A canker sore is a small lesion found in the mouth area. The direct cause of canker sores is still unknown. Dr. Edward Hill takes a closer look at canker sores in todayís 60 Second Housecall.
Canker sores are shallow, painful sores in your mouth. They are usually red. Sometimes they have a white coating over them. You might get them on the inside of your lips, the insides of your cheeks or under your tongue.
Canker sores are different from fever blisters, which usually are on the outside of your lips or the corners of your mouth.
If you have small canker sores you can treat them at home. You can try taking ibuprofen or acetaminophen for pain. Two other medicines called Orabase and Zilactin-B might keep your canker sores from becoming irritated by eating, drinking or brushing your teeth.
If your canker sores are large, last longer than a week or are so sore that you canít eat, you should make an appointment to see your doctor. Several prescription medicines may help with canker sores. You can talk about them with your doctor.
