Oral ulcer
An oral ulcer (from Latin ulcus) is the name for the appearance of an
open sore inside the mouth caused by a break in the
mucous membrane or the epithelium on the lips or surrounding the
mouth. The types of oral
ulcers are diverse, with a multitude of associated causes including: physical or chemical trauma, infection from
microorganisms or
viruses, medical conditions or medications, cancerous and sometimes nonspecific processes. Once formed, the ulcer may be maintained by inflammation and/or secondary infection. Two common oral ulcer types are
aphthous ulcers (canker sores) and cold sores, which are caused by the
herpes simplex virus.
