Scientists don't know what causes canker sores. Most believe that there is a problem with the body's immune system. Emotional stress, menstruation or injury to the mouth are common triggers for simple canker sores. Certain foods such as citrus or acidic foods may trigger a canker sore or make one more uncomfortable.
