Most mouth ulcers are caused by trauma (pizza burns) or stress (canker sores). People with weakened immune systems may be more susceptible to both canker sores and certain viral infections which show up as groups of small ulcers in the mouth. Trauma from an ill-fitting denture can also cause ulcers. More rarely, mouth ulcers may be caused by cancer.
