What is gingival recession?

Gingival recession is defined as the process where the gum tissue pulls back, exposing more of the tooth or its root. This condition occurs when the margin of gum tissue that surrounds the teeth wears away, exposing the underlying structures which can lead to sensitivity, aesthetics concerns, and increased susceptibility to decay or further periodontal issues.

The exposed areas can become more vulnerable to plaque accumulation and potential damage from bacteria, making it crucial to identify and address the underlying causes, which might include periodontal diseases, improper brushing techniques, or genetic predisposition. Understanding gingival recession is essential for proper diagnosis, management, and treatment planning in periodontal practice.

The other options describe different phenomena related to gum health, but they do not accurately capture the nature of gingival recession. For instance, the thickening of gum tissue refers to hyperplasia, and surgical procedures to enhance or grow gum tissue are typically related to gum grafting techniques.
