Gum is swollen in between teeth
Swelling between teeth usually reflects trapped plaque, food, or local gum inflammation, though an abscess can also cause a focused lump.
The short answer
Swelling between teeth usually reflects trapped plaque, food, or local gum inflammation, though an abscess can also cause a focused lump. The cause is identified by examining the gum, tooth contacts, and nearby tooth roots.
What is the direct answer?
What does this question mean?
The tissue between adjacent teeth is the interdental papilla. Food impaction, plaque at the gum margin, calculus, a cavity between teeth, or a periodontal pocket can make this tissue red, tender, and enlarged.
What can you do next?
Clean the contact gently with floss or an interdental brush sized to the space, then brush along the gumline with fluoride toothpaste. Do not force a sharp object into the swelling or repeatedly press it.
When should you seek dental care?
Book a dental examination if swelling persists, bleeds often, traps food, or is associated with toothache or a bad taste. Facial swelling, fever, spreading redness, or difficulty swallowing needs prompt urgent assessment.
What should you ask the dentist?
Ask whether the swelling comes from gingivitis, a periodontal pocket, food impaction, decay, or an infection at the root. Ask whether you need a bitewing radiograph, professional cleaning, or treatment for the tooth itself.
Frequently asked questions
Can food stuck between teeth make the gum swell?
Yes. Repeated food impaction can irritate the papilla and allow plaque to remain against it.
Is a swollen gum between teeth always an abscess?
No. An abscess is one possibility; examination distinguishes it from local gingival inflammation and other causes.
