My gum between my teeth is swollen
Swelling between teeth commonly reflects trapped plaque or food, gum inflammation, trauma, decay, or a localized dental infection.
The short answer
The triangular gum papilla between two teeth can swell when it is irritated or infected, and the cause determines the treatment.
What can irritate or infect the gum between teeth?
Food impaction, plaque, calculus, floss injury, a cavity near the contact point, or a periodontal pocket can inflame the papilla. A tooth-root infection may also drain toward the gum and form a tender bump.
How should you clean swollen gum between teeth?
Rinse gently with warm water, clean the contact with floss or an interdental brush without forcing it, and avoid squeezing the swelling. Do not place caustic substances on the gum or delay care if pain or swelling grows.
When should swollen gum between teeth be examined?
Arrange dental care if the swelling lasts, bleeds, recurs, or is linked to pain, bad taste, or a loose tooth. Facial swelling, fever, or difficulty opening the mouth, breathing, or swallowing needs urgent care.
What treatment may swollen gum between teeth require?
Ask whether the source is food impaction, gum disease, decay, or a tooth-root infection, and whether you need cleaning, a filling, root canal treatment, or periodontal care.
Frequently asked questions
Can food stuck between teeth cause swelling?
Yes. Repeated impaction can irritate the papilla and may point to a contact or tooth-shape problem.
Should I pop the swollen gum?
No. Popping it can injure tissue and does not remove an underlying infection.
