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.
Peptic ulcers, open sores in the lining of the stomach, esophagus, or duodenum (the first part of the intestine), are common. Contrary to popular belief, ulcers are not caused by spicy food or stress. Instead, a type of bacteria called Helicobacter pylori is usually to blame. Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), can also cause ulcers.
