What Does Plaque Mean?
The word plaque has several meanings depending on the context.

- Cavities
- Gum disease

Dentists frequently emphasize plaque control as an essential part of maintaining oral hygiene.
Commemorative Plaque
A plaque can also be a decorative or informational plate mounted on a wall, building, monument, or trophy.
Examples include:
- Historical building plaques
- Memorial plaques
- Employee recognition plaques
- Award plaques
These plaques typically contain engraved text or images.
Medical Plaque
In medicine, plaque may refer to abnormal deposits that accumulate inside the body.
Examples include:

Typing Errors
