Why is the gum beneath my tooth swollen?
Swollen gum beneath a tooth may result from plaque inflammation, trapped food, trauma, decay, or infection in the tooth or surrounding tissues.
What tissues support the gum around a tooth?
Gingiva surrounds the tooth and is supported by the periodontal ligament and jawbone. A local lump may be irritated gum, a periodontal pocket, a draining abscess, or pressure from an erupting tooth.
How should I clean beneath a swollen tooth?
Brush gently, clean between teeth, and rinse with warm salt water if soothing. Avoid sharp objects and placing aspirin directly on the gum.
When does swelling beneath a tooth need prompt care?
Arrange prompt care for pain on biting, pus, bad taste, fever, a loose tooth, or increasing swelling. Facial swelling or breathing or swallowing difficulty is an emergency.
Is the swelling in my gum or inside the tooth?
Ask whether the swelling is in the gum or comes from the pulp, and whether probing, X-rays, drainage, a filling, root canal, extraction, or gum treatment is needed.
