Infections can cause mouth ulcers. Herpes simplex often causes mouth ulcers in children and some adults. 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.
Diagnosing many common causes of mouth ulcers, such as oral thrush, cold sores and canker sores, can often be made by the symptoms and the appearance of the mouth ulcers. Making a diagnosis of mouth ulcers may also include performing a variety of tests to help to diagnose potential underlying diseases, conditions or disorders, such as oral cancer and leukoplakia.
