Periodontal Tissues

Photograph of athe longitudinal section of a tooth and its supporting tissue, showing the position of root, gum, alveolar bone and periodontal membrane.

Periodontal tissues are tissues surrounding the teeth. They have important functions:

  • Gingivae (gums)
    Cover the surface of alveolar bone. Healthy gingivae are pink in colour.

  • Alveolar bone
    Supports teeth. If alveolar bone is not healthy, the teeth will lose support, become loose, and fall out.

  • Periodontal membrane
    Attachment between teeth and alveolar bone.
