Swollen gums in a child can come from plaque-related inflammation, tooth eruption, food injury, decay, or an infection around a tooth..
The short answer
Swollen gums in a child can come from plaque-related inflammation, tooth eruption, food injury, decay, or an infection around a tooth.

What is the direct answer?
What does this question mean?
Gum swelling is an increase in the soft tissue around a tooth or along the gum margin. In children, eruption of a baby or permanent tooth can cause a localized tender area, while plaque, trapped food, cavities, or a dental abscess can produce redness and swelling.
What can you do next?
Look at the location, color, tenderness, drainage, fever, and the child’s ability to eat and open the mouth. Gently clean the area with a soft toothbrush, offer fluids and softer foods, and do not squeeze a lump or place aspirin on the gum.
When should you seek dental care?
A child should be seen promptly when swelling persists, recurs, drains, causes tooth pain, or comes with fever. Same-day urgent care is needed for swelling of the face, swelling near the eye, difficulty swallowing, breathing difficulty, marked tiredness, or inability to open the mouth normally.
What should you ask the dentist?
Is the swelling over an erupting tooth or beside a decayed tooth? Does the tooth need an X-ray? Is there an abscess or retained food? What pain relief and cleaning method fit the child’s age and medical history?
Frequently asked questions
Can teething explain every swollen gum?
No. Teething can cause localized tenderness, but swelling with pus, fever, significant pain, or facial enlargement needs assessment for infection or another cause.
Should a gum blister be popped?
No. Opening it can injure tissue and does not remove the dental cause; a dentist should assess persistent or draining swelling.
