What Is the Connection Between Canker Sores and Herpes?
Herpes lesions that present inside the mouth, known as cold sores, can be mistaken for a canker sore, or aphthous ulcer. Canker sores and herpes lesions are both open sores, however, their presentation and how and where the sores form are very different. Treatment for canker sores and herpes lesions can both involve the administration of topical and oral medications to reduce inflammation and aid with the healing process. Canker sores are oftentimes mistaken for cold sores, which are caused by the contagious herpes simplex virus. There is no known, definitive cause for the development of canker sores. Minor outbreaks of canker sores and herpes cold sores generally do not necessitate treatment. Persistent outbreaks of canker sores and herpes that are moderate to severe in presentation can require the use of topical and oral medications to speed the healing process.
