Which statement about the function of periodontium is true?

The periodontium refers to the supporting structures surrounding the teeth, which include the gums, periodontal ligaments, cementum, and alveolar bone. Its primary function is to help attach the tooth to the jawbone securely. This attachment is crucial for maintaining the stability of the tooth in the dental arch, allowing it to withstand the forces generated during chewing and other oral activities.

The periodontal ligaments play a significant role here; they connect the cementum of the tooth root to the alveolar bone and allow limited movement, which helps absorb stress while providing necessary support. By firmly anchoring the teeth, the periodontium helps to ensure proper alignment and functionality of the entire dentition.

Understanding the role of the periodontium is important in dental nursing, as it emphasizes the significance of maintaining oral health and periodontal health to prevent conditions such as periodontal disease, which can lead to tooth mobility or loss.
