What is the gingival sulcus?

The space preventing bacteria from forming
The area between the free gingiva and the tooth surface
An inflamed part of the gum tissue
The junction of the tooth and bone

The correct answer is: The area between the free gingiva and the tooth surface

The gingival sulcus is defined as the space between the free gingiva and the tooth surface. This space is important in dentistry because it plays a critical role in periodontal health. A healthy gingival sulcus typically measures around 1 to 3 millimeters in depth. Within this area, the gingival tissue attaches to the tooth, contributing to the overall stability of the periodontal structures. Understanding the gingival sulcus is vital for dental professionals, as it is also a site where plaque can accumulate, potentially leading to periodontal diseases if not maintained properly. Regular dental check-ups and cleanings help ensure that this sulcus remains healthy, preventing the onset of gum disease.
