What is the direct answer?
A gum swollen around one tooth can result from plaque irritation, trapped food, trauma, decay, or infection near the tooth.
What does this question mean?
A dentist checks the gum, tooth, pocket depth, bite, and sometimes an X-ray to identify the cause.
What can you do next?
Rinse gently with lukewarm water, clean carefully around the tooth, and avoid squeezing the swelling.
When should you seek dental care?
Arrange dental assessment promptly if swelling persists, pain increases, pus appears, or fever or facial swelling develops.
What should you ask the dentist?
Ask whether the swelling is in the gum or comes from the tooth root, and whether cleaning, a filling, drainage, or another treatment is needed.
Frequently asked questions
What will a dentist check?
The dentist examines the relevant teeth and oral tissues, reviews your history, and uses targeted tests or imaging when needed.
Can home care replace an examination?
Home care can reduce irritation, but it cannot identify or treat causes such as decay, pulp disease, or infection.
