Gingivitis vs. Periodontitis
The reversible stage — and the point beyond which the disease changes character.
Gingivitis is inflammation of the gum tissue in response to bacterial plaque. It is common, reversible, and — critically — the last stage at which no permanent damage has yet occurred.
The transition
Untreated, gingivitis can progress to periodontitis: the inflammation extends below the gumline and begins to destroy the supporting bone. This bone loss is not reversible; further loss is what treatment prevents.
Signals worth acting on
- Bleeding on brushing or flossing
- Persistent bad breath
- Receding gums or lengthening teeth
- Tooth mobility
