Swelling between two teeth

Swelling between two teeth commonly comes from inflamed gum tissue, trapped food, a periodontal pocket, or infection from a tooth.

The tissue between adjacent teeth is the interdental papilla; irritation may enlarge it, while an abscess can cause pus, bad taste, or biting pain.

A dentist examines both tooth surfaces, probes the gum, checks vitality and biting, and may take a radiograph.

Rinse gently, brush carefully, and use an interdental brush without force; never pierce the swelling or use sharp objects.

Arrange prompt care for persistent swelling, pus, fever, bad taste, toothache, or biting pain; facial swelling or swallowing difficulty is urgent.
