My teenage son suffers from regular bouts of mouth ulcers. They are very painful, and he is in pain for weeks until they subside. As a result, people often mistakenly think he is grumpy and disengaging when it is simply too sore for him to converse. His mouth hygiene is very good; he regularly visits the dentist, hygienist etc. Is there anything we can do to stop them from reoccurring or at least treat them when they do appear?
