What is one function of the periodontal ligament?

The function of the periodontal ligament is primarily to hold the tooth root securely in the socket. This specialized connective tissue fibers connect the tooth cementum, which is the hard tissue covering the tooth's root, to the alveolar bone of the jaw. This anchoring function is crucial as it provides stability to the tooth, allowing it to withstand the forces of biting and chewing while also maintaining its position within the dental arch.

The periodontal ligament also plays a role in shock absorption and sensory perception, but the key function highlighted in this context is its anchoring role. This structural support is significant in maintaining the integrity of the tooth within the oral cavity and contributes to overall dental health.
