My inner gum is swollen
Swelling on the tongue-side or cheek-side gum can reflect irritation, periodontal inflammation, an erupting tooth, or a dental infection.
The short answer
An inner-gum swelling is often caused by local irritation, plaque and calculus, an erupting tooth, or infection around a tooth.
Which gum tissues are meant by inner gum?
Inner gum means the gingiva on the tongue-side or palate-side of the teeth. The dentist examines its colour, firmness, bleeding, nearby tooth, and any drainage or ulcer.
How can you care for a swollen inner gum at home?
Keep the area clean with gentle brushing and interdental cleaning, and avoid sharp foods that rub it. Do not puncture or drain the swelling yourself.
When should persistent inner-gum swelling be examined?
Arrange care if the swelling lasts, enlarges, or is accompanied by tooth pain or pus. Urgent assessment is needed for spreading facial swelling or difficulty swallowing or breathing.
How can the dentist identify the source of the swelling?
Ask whether the swelling is in the gum, around a tooth root, or over an erupting tooth, and what examination or imaging will distinguish these causes.
Frequently asked questions
Could a sharp food injury cause this?
Yes. A local scrape or burn can swell, but persistent or worsening tissue still needs assessment.
What might drainage mean?
Drainage can come from an infection near a tooth, although examination is needed to confirm its source.
