My gum is swollen under one tooth
Swelling under one tooth may be gum inflammation, food impaction, irritation, or an abscess and needs a dental examination.
The short answer
Swelling under one tooth can come from localized gum inflammation, food impaction, an abscess, or irritation, and the tooth and surrounding tissues should be examined.

What is the direct answer?
What does this question mean?
A dentist checks the gum margin, pocket, tooth vitality, bite, and often an x-ray to distinguish a gum problem from infection inside the tooth.
What can you do next?
Clean gently with a soft brush and interdental aid, rinse with water, and avoid pressing the swelling or placing aspirin on it.
When should you seek dental care?
Seek prompt care if swelling persists or comes with throbbing pain, pus, fever, bad taste, or facial swelling. Trouble swallowing or breathing needs emergency help.
What should you ask the dentist?
Ask whether the swelling is in the gum, periodontal ligament, or root area, and what examination or x-ray findings determine treatment.
