From what part of the tooth do true pockets form?

True pockets, known as periodontal pockets, develop from the supporting tissues of the tooth, which include the periodontal ligament and alveolar bone. These pockets form as a result of periodontal disease, where inflammation and infection lead to the destruction of these supporting structures. The loss of attachment between the tooth and the surrounding tissues creates a space that characterizes a periodontal pocket.

Understanding this formation process is crucial for recognizing the progression of periodontal disease and the importance of maintaining healthy supporting tissues through good oral hygiene and regular dental check-ups. This also emphasizes the relationship between the health of the gums and the overall periodontal structure that supports the tooth, making awareness of these tissues vital in dental nursing practice.
