Why is a piece of my gum swollen
A small swollen gum area may result from trapped plaque, irritation, an erupting tooth, infection, or an abscess.
The short answer
A small swollen gum area may result from trapped plaque or food, irritation, an erupting tooth, gum infection, or an abscess beside a tooth.
What causes gum tissue to enlarge or form a bump?
Inflammation enlarges gum tissue as fluid and inflammatory cells collect; an abscess may form a pimple-like bump.
What can I do safely while the gum swelling settles?
Brush and clean between teeth gently, rinse with warm salt water, and do not squeeze or puncture the swelling.
When does a swollen gum area need dental assessment?
See a dentist if it lasts, grows, drains, bleeds easily, or returns. Fever or facial swelling needs urgent care.
Could the swelling come from my gum or an erupting tooth?
Is the swelling from the gum, a tooth root, or an erupting tooth, and is an X-ray needed?
