Both involve inflammation, but the consequence is different
Gingivitis refers to inflammation of the gingiva without loss of connective tissue attachment. Periodontitis involves inflammation plus destruction of the supporting apparatus, which means the history of the disease includes attachment loss and often bone loss.
Reversibility is the big conceptual divider
A helpful way to remember the difference is to ask whether the tissue changes are reversible with improved plaque control and care. Gingivitis is understood as reversible. Periodontitis reflects tissue destruction that cannot simply be undone by reducing surface inflammation.
Why this matters: many exam questions and clinical discussions hinge on whether you recognize attachment loss as the turning point.
Measurements and history shape the diagnosis
Bleeding, pocketing, recession, attachment levels, and radiographic findings all help build the full picture. A single visible sign rarely tells the entire story by itself.
- Inflammation alone does not define periodontitis
- Attachment loss adds historical context
- Charting helps connect what is seen to what is measured
