The short answer
A single swollen gum area can come from trapped food, local plaque, trauma, a gum pocket, or infection around a tooth. Persistent or painful swelling needs an examination.
What is the direct answer?
What does this question mean?
The swelling may be in the gingiva beside one tooth or a small abscess that drains through the gum. The cause can involve the tooth nerve, the periodontal tissues, an erupting wisdom tooth, or irritation from a sharp filling or food fragment.
What can you do next?
Rinse gently with warm water, continue careful brushing, and clean between the affected teeth if this does not cause severe pain. Do not puncture the swelling or place aspirin directly on the gum.
When should you seek dental care?
Arrange prompt dental care for swelling lasting beyond a short period, increasing pain, pus, fever, facial swelling, or difficulty opening the mouth. Emergency care is needed for trouble breathing or swallowing.
What should you ask the dentist?
Ask which tooth or tissue is causing the swelling. Ask whether you need a dental X-ray, drainage, decay treatment, gum treatment, or removal of a trapped irritant.
Frequently asked questions
Can I pop the swelling?
No. Puncturing it can worsen injury and does not treat the source.
Could it be an abscess?
Yes, a local swelling can be associated with infection, but examination is needed.
