Causes of canker sores.

The precise mechanism by which canker sores form has not been definitively determined but it is likely that their development is related to a reaction of an individual's own immune system.

Canker sores are thought to form when, for unexplained reasons, a person's immune system identifies the presence of chemical molecules that it does not recognize. The presence of these molecules activates an attack by the immune system's lymphocytes (a type of white blood cell), somewhat similar as when a person's immune system attacks a transplanted organ.
The carnage created by the lymphocytes' attack on these unrecognized molecules results in the formation of mouth ulcers. We term these ulcers canker sores.
