Why are the gums between my teeth swollen
Swelling between teeth often reflects inflammation of the interdental papilla from plaque, trapped food, a filling edge, or infection.
The short answer
The triangular gum tissue between teeth is the interdental papilla. Plaque, calculus, impacted food, a rough filling edge, periodontal disease, or a tooth infection can make it swell.
What can the exact location of swelling reveal?
A focused location is useful because the cause may be confined to one contact point or tooth. Bleeding, tenderness, bad taste, a pocket, or pain on biting helps distinguish surface inflammation from deeper disease.
How should you clean between swollen gums?
Gently clean the contact with floss or an appropriately sized interdental brush and brush along the gumline. Do not force a sharp object into the tissue.
When is swelling between teeth urgent?
Seek care promptly for increasing pain, pus, bad taste, fever, facial swelling, or difficulty opening the mouth, swallowing, or breathing. Recurrent swelling also needs assessment.
What should you ask about swelling between teeth?
Ask whether food impaction, gingivitis, periodontal pocketing, a restoration, or an abscess is responsible, and whether probing or an X-ray is indicated.
Frequently asked questions
Can this be diagnosed from one symptom alone?
Usually not. Location, duration, examination findings, and sometimes imaging determine the diagnosis.
What should I do while arranging care?
Use gentle oral hygiene, avoid aggravating the area, and seek prompt help for worsening pain, swelling, or functional difficulty.
