Which term describes the tissues that support and surround the teeth?

• A. Mucosa
• B. Dentin
• C. Alveolar bone
• D. Periodontal

Answer: (D)

The periodontium includes the tissues that surround and support teeth. This group comprises the gums (gingiva), the periodontal ligament that anchors the tooth to the bone, the cementum covering the tooth root, and the surrounding alveolar bone. Collectively, these structures form the periodontal tissues that hold teeth in place and protect their supporting structures. Mucosa is just the soft tissue lining the mouth, not the supporting tissues. Dentin is the tooth’s inner hard tissue beneath enamel, not the supporting framework. Alveolar bone is part of the supporting system, but the term that describes all the surrounding-supporting tissues together is periodontal.
