Bottom gums swollen
Swollen lower gums may result from plaque inflammation, a trapped food fragment, irritation, decay, or infection around a tooth.
The short answer
Swollen lower gums may result from plaque inflammation, a trapped food fragment, irritation, decay, or infection around a tooth. The pattern, tenderness, bleeding, and tooth response help a dentist identify the cause.
Where are the lower gums located around the bottom teeth?
The lower gingiva surrounds the roots and necks of the bottom teeth. General puffiness often reflects gingivitis, while one-sided swelling can point to local trauma, a periodontal pocket, or an abscess from the tooth pulp.
How can you care for swollen lower gums safely?
Clean gently with a soft brush and between the teeth, rinse with lukewarm water, and avoid squeezing the area. Clinical care may involve removing calculus or debris, treating decay, draining infection, or addressing a gum pocket.
When should swollen lower gums be checked by a dentist?
Arrange a visit if swelling lasts more than a brief irritation, bleeds repeatedly, or is painful when chewing. Fever, pus, facial swelling, or difficulty swallowing or breathing requires urgent assessment.
What should you ask about gum swelling and possible tooth causes?
Ask whether the swelling is in the gum or coming from a tooth, and whether an X-ray is needed. Ask what cleaning, filling, root canal, or periodontal treatment would resolve the identified cause.
Frequently asked questions
Can swollen gums be caused by a cavity?
Yes. A deep cavity can infect the pulp and tissues near the root, producing nearby gum swelling.
Should I massage the swelling?
No. Clean gently, but do not squeeze or massage a painful swelling.
