Gum between two teeth swollen
A swollen gum papilla between two teeth often reflects trapped plaque or food, but decay, calculus, trauma, and infection can also cause it.
The short answer
A swollen gum papilla between two teeth often reflects trapped plaque or food, but decay, calculus, trauma, and infection can also cause it. Gentle interdental cleaning may remove a local irritant, yet swelling that persists or hurts needs examination.

What is the direct answer?
What does this question mean?
The gum papilla is the small triangular tissue that fills the space beneath a tooth contact. Inflammation makes it red, enlarged, tender, or prone to bleeding, and a tight contact, cavity, rough filling, or gum pocket can keep the area irritated.
What can you do next?
Rinse with water, brush gently, and clean the space with floss or an appropriately sized interdental brush. Do not cut, squeeze, or repeatedly poke the swelling; note whether food traps there and avoid chewing hard foods on that side until it settles.
When should you seek dental care?
Book dental care if the swelling lasts, recurs in the same space, bleeds easily, or is accompanied by pain, pus, bad taste, or tooth sensitivity. Facial swelling, fever, or difficulty swallowing needs urgent assessment.
What should you ask the dentist?
Ask whether the contact, filling, tooth surface, or gum pocket is trapping plaque or food. Ask if you need a professional cleaning, a filling repair, periodontal treatment, or a different interdental cleaning tool.
Frequently asked questions
Can food stuck between teeth cause swelling?
Yes. Food and plaque can inflame the papilla, although a recurring problem may indicate a contact or tooth defect.
Is it okay to pop the swollen gum?
No. Puncturing or squeezing it can injure tissue and spread irritation; have the cause examined.
