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.
Causes of mouth ulcers. In most cases, mouth ulcers are not caused by an infection. This means they cannot be passed from person to person. For example, in most cases it is not possible to get a mouth ulcer from kissing someone who has a mouth ulcer, or by sharing drinking glasses or cutlery with them.
