Bump on top gum
A bump on the upper gum may be irritation, a blocked structure, or a draining tooth infection, so its location and duration matter.
The short answer
A small upper-gum bump can be caused by local irritation, a blocked tissue structure, a normal bony contour, or a sinus tract draining from an infected tooth. Its position beside a tooth, tenderness, color, and change over time help determine the cause.
Which tissues are found in the upper gum?
The upper gum contains mucosa, connective tissue, blood vessels, and the supporting tissues around tooth roots. A pimple-like swelling near a tooth can be a drainage point from an abscess, while a hard, stable prominence may be bone or another noninfectious structure.
What should you avoid doing to an upper-gum bump?
Do not squeeze or puncture the bump. Note when it appeared, rinse gently, brush carefully around it, and arrange an examination so the tooth, gum, and nearby structures can be tested; an X-ray may be needed if a root infection is suspected.
Which upper-gum symptoms need prompt dental care?
Seek prompt care for increasing swelling, severe toothache, fever, facial swelling, pus, or difficulty opening the mouth, swallowing, or breathing. A bump that persists, recurs, ulcerates, or bleeds also needs assessment.
What should the dentist identify beneath the bump?
Ask whether the bump arises from the tooth root, gum, bone, or soft tissue, whether imaging is needed, and what treatment addresses the cause. Ask what changes should prompt urgent review.
