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.
Stress/Injury. Any stress or injury located inside your mouth may be the root cause of a canker sore formation. Anything from brushing too hard, biting your gums, harsh mouthwashes, or eating something that causes bruising can lead to the tiny ulcers.If you are susceptible to canker sores, also try avoiding toothpastes and mouthwashes that contain sodium lauryl sulfate.nything from brushing too hard, biting your gums, harsh mouthwashes, or eating something that causes bruising can lead to the tiny ulcers.
