Other less common viral and bacterial infections may cause mouth ulcers, but this is rare. Mouth ulcers can be caused by anaemia and occasionally by other blood disorders, and some skin or gastrointestinal diseases. Sometimes the mouth ulcers are the only sign of an underlying disease.

They can also be caused by dental treatment, a sports injury or poorly fitting dentures. Bad diet: a diet lacking in certain vitamins, folic acid or iron can trigger the development of mouth ulcers.
