Gum bumps causes and treatment
A gum bump may come from irritation, a blocked gland, a cyst, or an infection, so its appearance and symptoms guide the next step.
The short answer
A gum bump may come from irritation, a blocked gland, a cyst, or an infection, so its appearance and symptoms guide the next step. A painful, pus-filled, or rapidly enlarging bump needs prompt assessment because it may be connected to a tooth or gum infection.

Where in the mouth can a gum bump develop?
The bump may be on the attached gum, the loose lining near the cheek, or behind a last molar. A dentist checks its color, firmness, tenderness, drainage, and relationship to the tooth root, jawbone, and nearby soft tissues.
How should you protect a gum bump until it is checked?
Keep the area clean with a soft brush and do not puncture, squeeze, or burn the bump. A dental examination may include a gum measurement, tooth vitality tests, and a dental X-ray before treatment such as cleaning, drainage, restoration, or removal of a lesion.
When should a recurring or changing gum bump be assessed?
Arrange dental care if the bump persists, returns, bleeds, or changes the way you bite. Seek urgent help for facial swelling, fever, difficulty swallowing, difficulty breathing, or swelling spreading toward the eye or neck.
Which mouth structure is causing the bump?
Ask whether the bump is arising from the gum, tooth, salivary tissue, or jawbone and whether an X-ray is needed. Ask which treatment addresses the cause, whether a sample is required, and what changes should prompt a return visit.
Frequently asked questions
Can a gum bump disappear on its own?
Some irritation settles, but a recurring or draining bump can indicate a dental source that still needs treatment.
Can a dentist tell what it is without touching it?
An examination usually includes looking and feeling the area, and an X-ray or other test may be needed to identify its source.
