Gum bumps causes symptoms and treatment
A bump on the gum may be irritation, a blocked tissue area, or a drainage point from an infected tooth, and its location and symptoms guide diagnosis.
The short answer
A gum bump is not one diagnosis: it can reflect trauma, a benign tissue change, or an abscess draining from a tooth or gum pocket.
Why might the gum around a bump become swollen?
Gum tissue can swell when plaque inflames it, when a tooth is erupting, or when a sharp edge repeatedly rubs it. A small pimple-like bump beside a painful tooth can be a sinus tract that drains infection from the root or periodontal tissues.
How can you protect a gum bump before assessment?
Do not squeeze or puncture the bump. Brush gently, keep the area clean, and note whether it is firm or soft, painful or painless, changing size, or releasing fluid; dental examination may include gum probing and an X-ray.
When does a gum bump need prompt dental care?
Seek prompt care for a painful bump, pus, fever, facial swelling, loose tooth, or difficulty opening the mouth. A persistent or enlarging lump also needs assessment even if it does not hurt.
What should the dentist check to identify a gum bump?
Ask whether the bump comes from the gum, tooth root, erupting tooth, or a local injury. Ask whether drainage, a filling, root canal treatment, gum treatment, or another procedure is needed.
