Swelling of gums around tooth
Gum swelling beside one tooth may reflect plaque, trapped food, trauma, decay, or infection.
The short answer
Swelling around one tooth can result from trapped plaque, gum inflammation, food impaction, trauma, decay, or infection near the root. The cause determines whether cleaning, a filling, gum care, or infection treatment is needed.

What is the direct answer?
What does this question mean?
The location, colour, tenderness, bleeding, drainage, and condition of the tooth help distinguish irritated gum from a deeper abscess. The exact pattern helps locate the affected tissue.
What can you do next?
Brush softly along the gumline, clean between the teeth without forcing the swollen area, rinse with warm water, and avoid squeezing it. These measures support comfort while the cause is assessed.
When should you seek dental care?
Arrange prompt care if swelling grows, becomes painful, drains, causes fever, or spreads into the face or neck. Urgency depends on progression and associated symptoms.
What should you ask the dentist?
Ask whether the swelling is in the gum pocket or at the root, and whether a periodontal examination or X-ray is needed. The answers guide a focused examination and treatment plan.
Frequently asked questions
What is the usual first step?
Ask whether the swelling is in the gum pocket or at the root, and whether a periodontal examination or X-ray is needed.
Can home care replace treatment?
Home care can support hygiene or comfort, but it cannot repair damaged tooth structure, remove calculus, or drain a dental infection.
