Dental Admissions Test (DAT) Practice Test

Gingivitis is the condition characterized by inflammation at the gum line. This inflammation typically results from the accumulation of plaque, a sticky film of bacteria that develops on the teeth. When the plaque is not effectively removed through brushing and flossing, it can irritate the gum tissue, leading to swelling, redness, and bleeding, especially during brushing or flossing.

Gingivitis is often considered the initial stage of periodontal disease and, if left untreated, may progress to more severe forms of gum disease. The condition is generally reversible with good oral hygiene practices, including regular dental cleanings and improved home care.

In contrast, periodontitis involves deeper inflammation that affects the supporting structures of the teeth, and dental caries refer to tooth decay caused by acids produced by bacteria in plaque. Oral thrush is a fungal infection in the mouth, not directly linked to inflammation at the gum line. Understanding these distinctions helps clarify why gingivitis is specifically identified as the condition involving inflammation primarily at the gum line.
