Question: 1 / 1775

Which term is used to describe an ulcer found in the mouth that is typically painful?

Canker sore

The term for an ulcer found in the mouth that is typically painful is canker sore. Canker sores, also known as aphthous ulcers, are small, shallow lesions that develop on the soft tissues inside the mouth or at the base of the gums. They can cause significant discomfort and are often triggered by stress, certain foods, or injury to the mouth.

Herpes simplex refers to the viral infection that can cause cold sores or fever blisters, usually on the lips or around the mouth, rather than ulcers in the mouth. Oral thrush is a fungal infection characterized by white patches in the oral cavity and does not typically manifest as painful ulcers. Lastly, a periodontal abscess is a localized infection in the gums that generally occurs due to advanced gum disease and can be painful, but it is not classified as an ulcer. Thus, canker sore is the most accurate term for a painful mouth ulcer.
