Swollen Gum Between Two Teeth?
Swelling between two teeth often comes from trapped food or local inflammation; learn other causes and when a dentist should check the area.
The short answer
A small swelling between two teeth is commonly linked to trapped food or local gum inflammation, but a periodontal pocket, foreign object, or tooth infection can also cause it.
What is the triangular gum between neighbouring teeth?
The triangular gum between neighbouring teeth is called the interdental papilla. Plaque, a tight contact, a rough filling edge, a food fragment, gum disease, or an abscess near a tooth root can make this tissue red, tender, enlarged, or prone to bleeding.
How can you clean swelling between two teeth?
Gently floss or use an appropriately sized interdental brush, then brush the gumline with a soft brush. Do not force an object into the space or puncture the swelling; note bleeding, pus, bad taste, pain on biting, and changes in tooth contact.
When should swelling between teeth be checked?
Seek care if the lump remains after careful cleaning, returns in the same place, bleeds, drains, or is paired with toothache. Facial swelling, fever, or trouble swallowing needs urgent assessment.
What could be causing swelling between two teeth?
Ask whether the swelling is in the papilla, a gum pocket, or an abscess, and whether probing, a filling adjustment, cleaning, or a dental radiograph is needed.
Frequently asked questions
Can home care fix the underlying problem?
Home care can protect tissue or reduce symptoms, but decay, infection, structural damage, and persistent lesions need diagnosis and treatment.
What information helps at an appointment?
Record when it started, what triggers it, whether it bleeds or swells, and any treatment or product already used.
