Swollen gum cavity
A swollen gum beside a cavity can indicate trapped plaque, food, pulp infection, or an abscess and needs examination.
The short answer
A cavity is a defect caused by tooth decay, while gum swelling is enlargement of nearby gingival tissue. When they occur together, the swelling may be beside the crown or may reflect infection extending from the pulp through the root.
