What could a bump under my tooth mean?

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.

Why can a tooth infection form a gum pimple?

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.

How should I protect a bump beneath my tooth?

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 does a bump under a tooth need prompt 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 I ask about the swelling beneath my tooth?

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.
