Swelling above upper teeth
Swelling above an upper tooth can come from a gum problem, a tooth-root infection, trauma, or a blocked sinus, and a dentist should identify the source.
The short answer
A lump or swelling above an upper tooth is a sign of inflamed tissue, not a diagnosis by itself. An infected pulp can drain through bone into the gum, but gum disease, trauma, and nearby sinus inflammation can produce similar symptoms.

What is the direct answer?
What does this question mean?
The roots of upper teeth lie close to the maxillary sinus and facial tissues. The dentist checks the tooth’s response to cold or electrical testing, taps and bites the tooth, examines the gum, and uses a focused radiograph when indicated.
What can you do next?
Keep the area clean and avoid squeezing or puncturing the swelling. Arrange an examination because drainage through the gum can reduce pressure without removing the source inside the tooth; treatment may involve a filling, root canal treatment, gum care, or extraction depending on findings.
When should you seek dental care?
Seek prompt care for increasing swelling, fever, facial redness, severe pain, or a bad taste with pus. Emergency help is needed for swelling near the eye or difficulty breathing or swallowing.
What should you ask the dentist?
Is the swelling coming from the tooth pulp, gum, sinus, or trauma? Ask what tests show, whether drainage is needed, and which treatment removes the underlying source.
Frequently asked questions
Can a dental abscess disappear by itself?
Pain or swelling may fluctuate, but the source can remain and needs dental assessment.
Is swelling above a tooth always an abscess?
No. Examination is needed because gum, sinus, and trauma can cause similar swelling.
