What is the direct answer?

Swelling behind a back tooth can come from a wisdom tooth, trapped food, gum inflammation, trauma, or infection around a nearby tooth.

What does this question mean?

The rear gum may cover a partly erupted third molar, or a nearby molar may have plaque, decay, or a periodontal pocket. Trauma, an ulcer, and infection can feel similar.

What can you do next?

Rinse gently with warm salt water, clean carefully with a small soft brush, and prevent food packing there. Do not cut the gum, squeeze it, or force a tooth to move.

When should you seek dental care?

Arrange prompt care for persistent or recurrent swelling, drainage, bad taste, limited opening, or fever. Neck or facial spread, breathing difficulty, or swallowing difficulty is urgent.

What should you ask the dentist?

Ask whether a wisdom tooth, gum pocket, ulcer, or abscess is responsible and whether an X-ray or treatment is needed.

Frequently asked questions

What is the most likely cause?

The rear gum may cover a partly erupted third molar, or a nearby molar may have plaque, decay, or a periodontal pocket. Trauma, an ulcer, and infection can feel similar.

Can it improve without treatment?

Some irritation settles when its trigger is removed, but persistent, recurrent, painful, or swollen symptoms need an examination.
