Could a blister above a tooth be a draining abscess?

A blister-like bump above a tooth may be a draining abscess and needs examination to find and treat its source.

What is happening inside a dental abscess?

A dental abscess is a pocket of pus around a tooth root or in the gum. A sinus tract can carry drainage through the gum above the affected tooth.

What should you avoid doing to a gum blister?

Do not squeeze or puncture the bump. Brush gently, rinse carefully, and arrange an examination with an X-ray to assess the tooth root and surrounding bone.

When does a blister above a tooth need prompt care?

Seek prompt care for a recurrent bump, pain, fever, bad taste, or facial swelling. Breathing or swallowing difficulty requires emergency assessment.

What treatment might be needed for the swollen gum?

Ask whether the swelling drains from the tooth root, whether the pulp is infected, and whether root canal treatment or another procedure is needed.

Frequently asked questions

Can an abscess bump disappear?

It may flatten when fluid drains, but the source can remain and return.

Is a gum blister always an abscess?

No. Trauma and other lesions can look similar, so a persistent bump needs examination.
