What effect does periodontal disease have on tooth mobility?

Periodontal disease significantly impacts tooth mobility, primarily by increasing it. Inflammation from periodontitis affects the supporting structures of the teeth, including the periodontal ligament and alveolar bone. As the disease progresses, it leads to the destruction of these supportive tissues, causing a loss of attachment and bone around the teeth. This reduction in support allows the teeth to become more mobile.

The progressive nature of periodontal disease means that as it advances, the attachment between the tooth and bone deteriorates, further contributing to instability. Therefore, individuals with periodontal disease commonly experience increased tooth mobility, which is a key indicator of the severity of the condition. Recognizing this change is crucial for dental professionals in diagnosing and managing periodontal disease effectively.

Other options do not accurately reflect the relationship between periodontal disease and tooth mobility, as healthy periodontal tissues maintain tooth stability, while disease disrupts these structures.
