What causes swelling in the gums
Swollen gums can result from plaque-related inflammation, infection, trauma, or hormonal changes and need assessment if persistent.
The short answer
Swollen gums are most often caused by inflammation from plaque, but infection, trauma, trapped food, medicines, or hormonal changes can also contribute. The cause depends on whether the swelling is general or limited to one tooth.
What is the direct answer?
What does this question mean?
Gingival swelling means the gum tissue has increased fluid and blood flow as part of inflammation. Redness, bleeding during brushing, tenderness, bad taste, or a small lump can help distinguish simple gingivitis from a tooth or gum abscess.
What can you do next?
Brush along the gum margin twice daily with a soft brush and clean between the teeth. Rinse with lukewarm water, avoid picking at the swelling, and do not place aspirin or other chemicals directly on the gum.
When should you seek dental care?
Book a dental examination when swelling persists, recurs, bleeds easily, or occurs around a painful tooth. Seek urgent care for rapidly spreading facial swelling, fever, difficulty swallowing, breathing difficulty, or restricted mouth opening.
What should you ask the dentist?
Ask whether the swelling is gingivitis, periodontitis, an abscess, or irritation from a tooth or appliance. Ask whether you need periodontal measurements, dental radiographs, professional cleaning, drainage, or treatment of a specific tooth.
Frequently asked questions
Can food stuck between teeth swell the gum?
Yes. Local irritation from trapped food can inflame one gum area, although persistent swelling needs examination.
Will brushing make swollen gums worse?
Gentle brushing removes plaque and usually supports healing; forceful scrubbing can further irritate the tissue.
