What are aphthous ulcers commonly known as?

Aphthous ulcers are commonly referred to as canker sores. These are small, painful lesions that typically appear on the soft tissues inside the mouth, such as the cheeks and gums, and can also occur at the base of the gums. Canker sores are characterized by their round or oval shape, often with a white or yellow center and a red halo around them. They differ from other oral lesions, such as cold sores, which are caused by the herpes simplex virus, and appear on the outside of the lips or the area surrounding the mouth.

Understanding aphthous ulcers as canker sores is essential for proper identification and treatment, as they are often confused with similar oral conditions, but they have distinct causes and treatment approaches. Knowing the correct terminology helps in better communication regarding oral health issues and aids in appropriate self-care and management strategies for those affected.
