Swelling around gums
Gum swelling can come from plaque-related inflammation, a trapped irritant, an erupting tooth, or infection in a tooth or gum pocket.
The short answer
Gum swelling can come from plaque-related inflammation, a trapped irritant, an erupting tooth, or infection in a tooth or gum pocket. The location, tenderness, discharge, and tooth response help identify the source.

What is the direct answer?
What does this question mean?
Swelling is an increase in tissue fluid or inflammatory tissue around the gingiva. It may be a broad thickening along several teeth or a localized lump beside one tooth, and the gum itself may not be the original source.
What can you do next?
Brush gently, clean between the affected teeth, rinse with water, and avoid squeezing or piercing the area. A dentist may examine the pocket, test pulp vitality, take a radiograph, remove a trapped irritant, drain an abscess, or treat the tooth or gums.
When should you seek dental care?
Arrange prompt care for pus, a painful lump, fever, spreading facial swelling, or worsening pain. Breathing or swallowing difficulty is an emergency because swelling can involve deeper tissues.
What should you ask the dentist?
Ask whether the source is gum tissue, a periodontal pocket, tooth pulp, or an erupting tooth. Ask what the examination and radiograph show, whether drainage or root canal treatment is needed, and how recurrence will be prevented.
Frequently asked questions
Can a gum abscess disappear on its own?
Drainage may reduce temporarily, but the source still needs dental assessment and treatment.
Should I put aspirin on the swelling?
Do not place aspirin or caustic substances on gum tissue; arrange dental advice instead.
