Swollen gums between teeth causes and dental evaluation
Swelling between teeth often reflects inflamed gum tissue, trapped food, trauma, or a localized infection.
The short answer
Gum swelling between teeth often reflects plaque-induced gingival inflammation, trapped food, trauma, or a localized infection, and the cause is found by examining the gum and tooth.
How can you clean around swollen gum tissue?
Brush gently at the gumline and clean between the teeth with floss or an appropriately sized interdental brush. Do not puncture the swelling or place aspirin on it; note bleeding, discharge, pain, and how long it has been present.
When does swelling between teeth need prompt care?
Seek prompt care for pus, increasing pain, fever, facial swelling, a loose tooth, or difficulty opening the mouth, swallowing, or breathing. Persistent swelling without severe pain also needs examination.
What should you ask about swelling between teeth?
Ask whether the swelling is gingivitis, periodontal disease, food impaction, trauma, decay, or an abscess. Ask whether pocket measurements, a cleaning, or a dental radiograph is needed.
