What is the direct answer?

A bump beneath a tooth can come from irritated gum tissue, a draining dental infection, a cyst, or normal anatomy, so its cause needs an examination.

What does this question mean?

A small pimple that releases fluid can occur when infection from the pulp or root reaches the gum. A firm, painless swelling can have a different cause, including a bony or soft-tissue change.

What can you do next?

Keep the area clean with a soft brush and do not squeeze or puncture the bump. Note when it appeared, whether it drains, and whether the tooth reacts to temperature or biting.

When should you seek dental care?

Arrange prompt care for increasing pain, facial swelling, fever, pus, a loose tooth, difficulty swallowing or breathing, or a bump that persists or changes.

What should you ask the dentist?

Ask whether the swelling is connected to the tooth, whether an X-ray is needed, and whether treatment involves the gum, a filling, root canal treatment, extraction, or observation.
