Abscesses of the periodontium
- gingival abscesses
- periodontal abscesses
- pericoronal abscesses
- combined periodontal/endodontic abscesses
The fourth type will be dealt with in its own article because of its often distinct etiology.
An abscess of the periodontal tissue is termed a periodontal abscess when the localized, purulent infection involves a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket. Such a lesion may contribute to destruction of the periodontal ligament and alveolar bone.
An abscess of the periodontal tissue is termed a pericoronal abscess when the localized, purulent infection exists within the gum tissue surrounding the crown of a partially or fully erupted tooth. This is also referred to as pericoronitis.
All three of these types of abscesses will present as red, swollen lesions that are painful to touch. They may possess a shiny surface representative of the stretching of the mucosa over the abscess. Pus may be present.
