Dental question about observed-topic:taxonomy-symptom-swollen-gums
Swollen gums usually reflect plaque-related inflammation, but pain, pus, fever, or spreading swelling needs prompt dental assessment.
The short answer
Swollen gums are usually caused by inflammation at the gum margin from plaque, trapped food, or infection, and the right response is gentle cleaning plus dental assessment when symptoms persist or are severe.

What is the direct answer?
What does this question mean?
The gingiva can enlarge when blood vessels and immune cells respond to bacteria around the teeth. Local swelling beside one tooth may also reflect a cavity, a gum pocket, an erupting tooth, or an abscess.
What can you do next?
Brush the gumline with a soft toothbrush, clean between the teeth with floss or an interdental brush, and rinse with lukewarm water. Do not puncture the swelling or place aspirin directly on the gum; arrange an examination to remove calculus or treat the tooth if the irritation continues.
When should you seek dental care?
Book dental care promptly for persistent bleeding, pus, a bad taste, increasing pain, or a lump beside a tooth. Seek urgent medical help if swelling spreads into the face or neck, or if breathing, swallowing, or opening the mouth becomes difficult.
What should you ask the dentist?
Ask whether the swelling is from gingivitis, periodontal disease, a cavity, an erupting tooth, or an abscess, and whether an X-ray is needed. Ask which cleaning method, periodontal treatment, or tooth treatment will address the cause.
Frequently asked questions
Can swollen gums go away on their own?
Mild irritation may settle after plaque and trapped food are removed, but recurring or localized swelling needs a dental examination to find the cause.
Why is one area of gum swollen?
A single swollen area can be associated with food impaction, a deep gum pocket, decay, an erupting tooth, or an abscess near the root.
