What do it mean when your gums swell up
Swollen gums indicate inflammation or irritation, often from plaque, but a trapped food particle, infection, medication, or another oral condition can als.
The short answer
Swollen gums indicate inflammation or irritation, often from plaque, but a trapped food particle, infection, medication, or another oral condition can also be involved.
What does swelling tell you about inflammation in your gums?
Swelling means the gum tissue contains extra fluid and inflammatory cells. Plaque-induced gingivitis is common, but a food impaction, erupting tooth, abscess, trauma, mouth ulcer, or irritation from an appliance can produce a similar appearance.
What should you check when a swollen gum first appears?
Look for the location, duration, tenderness, bleeding, discharge, bad taste, and whether a tooth hurts when biting. Gentle brushing and interdental cleaning help plaque-related swelling, but squeezing a lump or applying household chemicals can injure tissue.
When can swollen gums signal a need for same-day care?
Seek same-day care for swelling with toothache, pus, fever, facial swelling, or difficulty opening the mouth. Emergency help is needed when swelling affects breathing or swallowing.
How can your dentist identify the cause of gum swelling?
Ask whether the swelling comes from the gum or a tooth, whether an X-ray is needed, and what treatment will remove the cause rather than only reducing the swelling.
