Puffy gums around tooth
Puffy gum tissue around one tooth can result from plaque, food impaction, trauma, decay, or infection near the tooth.
The short answer
Puffy gums around one tooth are commonly caused by local irritation, trapped food, gum inflammation, decay, or infection from the tooth or its supporting tissues.

What is the direct answer?
What does this question mean?
The gum, or gingiva, forms a seal around the tooth and covers the jawbone. Swelling may be soft and red from inflammation, or may form a tender pocket when fluid or pus collects beside a tooth.
What can you do next?
Brush gently along the gum margin and clean between the teeth with floss or an interdental brush if it does not cause sharp pain. Do not squeeze the swelling or place aspirin, alcohol, or caustic products on the gum.
When should you seek dental care?
Arrange a dental examination if swelling persists, recurs, bleeds, tastes unpleasant, or is linked with pain or sensitivity. Facial swelling, fever, worsening pain, or difficulty opening the mouth or swallowing needs urgent assessment.
What should you ask the dentist?
Ask whether the swelling is from the gum margin, a periodontal pocket, a cavity, a cracked tooth, or an abscess. Ask whether probing, an X-ray, cleaning, filling, root canal treatment, or drainage is needed.
Frequently asked questions
Can food stuck between teeth cause a gum lump?
Yes. Food impaction can inflame the papilla between teeth, but persistent swelling still needs examination for decay or periodontal disease.
Should I pop a gum swelling?
No. Squeezing can injure tissue and does not treat an infected tooth or periodontal pocket.
