Canker sores are a form of ulcer, which the medical establishment now reluctantly agrees is a microbiotic infection treatable with anti-biotics.
Depending on the advancement of the case, early sores can be treated by simply eating a small tub of yoghurt every day.
Advanced cases require a course of anti-biotics.
Prevention is usually about stabilising the ph conditions in your mouth. Changing toothpaste, altering dietary habits and regular use of mouthwash can go a long way to prevention, as can regular intake of pro-biotics such as yoghurt and other culture rich foods.
Note, I am not that kind of doctor, but always happy to help where I can.
