Canker Sores

Read more about...

Canker sores are small, swollen, painful ulcers that occur on the lips or in the mouth. Canker sores hurt. When you develop a canker sore, you may not even want to eat. Acidic foods sting. Even the act of chewing can cause irritation in the area.

A canker sore begins as a small red dot on the lip or the inside of the mouth, which then develops into a vesicle with a white head. Eventually the head will rupture, leaving an open ulcer that can become secondarily infected by yeast or bacteria.

The cause of the original ulcer may be difficult to pinpoint, although food allergies, vitamin deficiencies, acidic conditions, and small cuts are probable cause. There is also some research that indicates an autommune phenomenon may be at work.

Canker sores and cold sores look very much alike. Cold sores however are caused by the herpes virus, which is highly contagious. Typically herpes sores appear on the hard part of the gums or the dry part of the lips, while canker sores occur on the loose part of the gums the insides of the cheeks, or the inner lip. Also cold sores tend to recur at exactly the same place every time, while canker sores can occur anywhere in the mouth.
