An abscess that develops on the gums is often referred to as a gum boil.
They appear as swollen bumps on the gum.
The main cause of a gum boil is bacteria — often from plaque, food particles, or tooth decay — that leads to infection beneath the surface of the gum.
Rarely, a gum boil is a symptom of oral cancer.
Based on where the gum boil is located, it’s categorized as one of three types:
°in the gum line: gingival abscess
°at the root of the tooth: periapical abscess
°in the supporting tissues of the teeth: periodontal abscess
