Periodontal disease is a type of disease that affects one or more of the periodontal tissues:
- alveolar bone
- periodontal ligament
- cementum
- gingiva
While many different diseases affect the tooth-supporting structures, plaque-induced inflammatory lesions make up the vast majority of periodontal diseases and have traditionally been divided into two categories:
- gingivitis or
- periodontitis.
While in some sites or individuals, gingivitis never progresses to periodontitis, data indicate that periodontitis is always preceded by gingivitis.

“All my humor is based upon destruction and despair. If the whole world were tranquil, without disease and violence, I’d be standing on the breadline right in back of J. Edgar Hoover.”
