To understand gingivitis, it is important to have an idea of the anatomy
of the tooth and its supporting structure.
 |
When a tooth is clean, the gums around it are usually pink and
healthy.
|
 |
If the tooth is not properly cleaned, plaque forms and accumulates
on its surface.
Plaque is a sticky layer of bacteria (very small germs) that grows
on any tooth surface, even between the teeth.
|
 |
Plaque causes irritation of the gums. The gums usually become red
and slightly swollen.
This condition is called gingivitis.
|
 |
When gingivitis is present:
- Pocket depth may increase due to swelling.
- The gums may bleed more easily when touched.
- The bone level does not change around the tooth.
|
Almost all advanced periodontal
diseases start with gingivitis.
