Which stage of periodontitis is associated with irreversible damage?

The stage of periodontitis associated with irreversible damage is the severe stage. In severe periodontitis, significant bone loss occurs, and the structure supporting the teeth is compromised. This damage can lead to tooth mobility and potential tooth loss, which cannot be reversed even with treatment.

At this stage, the periodontal attachment has suffered extensive destruction, resulting in deep periodontal pockets and the proliferation of harmful bacteria. Effective management may control the condition and prevent further deterioration, but the irreversible aspects of the damage imply that the effects on the periodontium are permanent. Understanding these stages highlights the importance of early detection and intervention in managing periodontal disease to prevent progression to irreversible damage.
