Mouth ulcers

What is it?

They are painful shallow ulcers (sores) in the lining of the mouth, usually on the inside of lips, inside of cheeks, and gums. They are caused by many disorders. Aphthous ulcer is most common in young adults. Some may result from prolon ged contact with food that gets stuck in the teeth. Others may be due to forgotten injuries from toothbrushes, toothpicks, rough foods (such as corn chips), hot foods, or self-biting. Herpes simplex causes recurrent blisters on the outer lip but does no t cause recurrent canker sores on the inside of the mouth. Other causes include canker sores, oral cancer, oral lichen planus, oral thrush, and other disorders.

The appearance and exact location of lesions varies with the specific disorder.
