What is the direct answer?

A gum bump may be irritation, an eruption-related swelling, or a drainage point from an infected tooth, so its cause needs examination.

What does this question mean?

The gum, or gingiva, can swell when it is rubbed, infected, or responding to a tooth beneath it. A small pimple-like bump beside a tooth can be a sinus tract that drains inflammation from the tooth root.

What can you do next?

Rinse gently with warm water, keep brushing around the area, and do not pop, cut, or repeatedly press the lump. Note its size, colour, tenderness, and how long it has been present.

When should you seek dental care?

Seek prompt care if the bump is painful, draining, enlarging, associated with fever or facial swelling, or has not settled after a short period. Difficulty breathing or swallowing needs emergency help.

What should you ask the dentist?

Ask whether the swelling is in the gum or bone, whether an X-ray or vitality test is needed, and whether the tooth or a local irritant is responsible.

Frequently asked questions

Can a gum bump disappear on its own?

Some irritation settles when the cause is removed, but a draining bump from an infected tooth can persist or recur without treatment.

Should I squeeze a gum pimple?

No. Squeezing can injure tissue and does not remove infection inside a tooth or under the gum.
