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.
Mouth ulcers are tiny breaks in the lining of the mouth or on the tongue that form painful flat sores. Theyâre thought to be caused by a virus. They mainly occur when your child has been ill or tired, as well as during stressful times. These types of ulcers are often referred to as âaphthous ulcersâ or âcanker soresâ.
