Which term refers to the tissues surrounding and supporting the teeth?

• A. Periodontal
• B. Posterior
• C. Root Canal
• D. Tartar

Answer: (A)

The tissues that surround and support the teeth are called the periodontium, and the term used to describe them is periodontal. This collection of structures includes the gingiva (gums), cementum that covers the tooth roots, the periodontal ligament that anchors teeth to the jaw, and the alveolar bone that forms the tooth sockets. Together, these tissues stabilize teeth, absorb chewing forces, and help protect them from injury. The other terms don’t fit: posterior refers to a location at the back of the mouth; root canal is the hollow space inside the tooth’s root containing pulp; tartar is a hardened plaque on tooth surfaces.
