In brief: Canker sores?

Canker sores are ulcers of unknown origin.
They may result from stress, citrus foods, irritation or trauma. They usually occur on the inside of the mouth and the tongue. Aphthous stomatitis (cold sores or fever blisters) are caused by the hsv-1 virus. They usually occur in clusters on the outside of the lips. Check with your dentist for a definitive diagnosis and treatment for pain.
