The short answer
Swelling inside the gum can be caused by plaque-related inflammation, trauma, a cyst, or infection from a tooth, and the cause is identified by examining the tooth and surrounding tissue.

What does a bump inside the gum indicate?
A gum bump is a localized change in the gingiva or the tissue over a tooth root. Its colour, firmness, tenderness, drainage, relationship to a tooth, and duration help distinguish irritation from a deeper lesion.
How can you care for a swollen gum bump now?
Keep the area clean with gentle brushing, avoid puncturing the swelling, and note any nearby tooth sensitivity or discharge. A dentist may probe the gums, test nearby teeth, and use an X-ray to locate decay, bone changes, or an abscess.
When does a gum bump need prompt dental care?
Arrange dental care promptly if the bump persists, grows, drains, or is painful, especially with toothache or fever. Facial swelling or difficulty swallowing or breathing requires urgent help.
What should you ask about a swollen gum bump?
Ask what tissue is swollen, whether a tooth is the source, what imaging or tests are needed, and whether treatment requires cleaning, drainage, root canal treatment, or removal of the tooth.
