Swollen gums pus around tooth
Swollen gums with pus often indicate a localized infection around a tooth or gum pocket and need prompt dental examination.
The short answer
Pus is an inflammatory fluid containing immune cells, bacteria, and tissue debris; a gum swelling that drains pus should not be squeezed or ignored.
Where can an abscess causing gum pus begin?
A dental abscess may begin in the pulp inside a tooth or in periodontal tissues beside the root. Pressure can create a gum boil that drains through a small opening, sometimes reducing pain without removing the infection source.
What should you do when a gum swelling drains pus?
Rinse gently, keep brushing around the area, and arrange prompt dental care for examination and dental imaging. Treatment may involve drainage, cleaning a periodontal pocket, root canal treatment, extraction, or another procedure selected after the source is identified.
When is pus from a swollen gum an urgent problem?
Seek urgent care for spreading facial swelling, fever, worsening illness, difficulty opening the mouth, swallowing, or breathing. Even if pus drains and the pain improves, the infected tooth or gum still requires assessment.
How can the dentist identify where the pus comes from?
Is the pus coming from the tooth pulp, a gum pocket, or another nearby structure? Ask how the examination will change the treatment recommendation.
Frequently asked questions
Can a gum abscess heal by itself?
Drainage may ease pressure, but it does not reliably remove the infected source or restore damaged tooth tissue.
Should I pop the swelling?
No. Squeezing or cutting it can injure tissue and does not treat the infection source.
