What does free gingiva form around?

1. The tooth root

2. The gingival sulcus

3. The alveolar bone

4. The periodontal ligament

The correct answer is: The gingival sulcus

Free gingiva forms around the gingival sulcus, which is the space between the tooth and the free gingiva. This area plays a significant role in oral health, as the health of the gingiva and the gingival sulcus is critical for preventing periodontal disease. The free gingiva is the part of the gum tissue that is not directly attached to the tooth surface, allowing it to create a cuff-like structure that surrounds the tooth and helps to protect the underlying structures. Understanding the gingival sulcus is crucial because it serves as a barrier against bacteria and debris. Proper maintenance of this area is essential, as a healthy sulcus can help prevent the development of gum disease. If the sulcus becomes deepened through inflammation or infection, it can indicate periodontal issues, which is why the free gingiva's role around it is so important.
