Gum swollen above one tooth

A swollen gum above one tooth can come from plaque, food impaction, trauma, a gum pocket, or infection from the tooth’s pulp or root.

The swelling may be gum inflammation or a localised abscess; pain on biting or a draining spot can point toward the tooth.

Keep it clean, do not squeeze it, and have the dentist examine the tooth, test the pulp, probe the gum, and take an indicated radiograph.

Seek prompt care for persistent swelling, pus, toothache, fever, facial swelling, or difficulty swallowing or breathing.

Ask whether the source is the gum or tooth and whether drainage, root-canal treatment, or another procedure is needed.
