Swollen inner gum teeth
A swollen area on the inner gum can result from irritation, plaque-related inflammation, a trapped food particle, or infection near a tooth.
The short answer
Swelling on the inner gum is not a diagnosis by itself; its cause may be in the gum, tooth, or surrounding tissue.
What is the inner gum beside the teeth?
The inner gum is the oral mucosa and gingiva on the tongue or palate side of the teeth. Localized swelling can reflect inflamed gum tissue, a periodontal pocket, a draining dental abscess, trauma from biting, or a developing tooth.
How can you clean around swelling on the inner gum?
Rinse gently with warm water, brush with a soft toothbrush, and clean between the teeth without digging into the swelling. Do not pierce it or place aspirin, alcohol, or concentrated chemicals on the gum; arrange an examination if it persists or is tender.
Which symptoms mean inner gum swelling needs care?
Arrange prompt dental care for pus, a bad taste, toothache, increasing swelling, or pain when biting. Seek urgent medical help for swelling that spreads into the face or neck, fever, trouble swallowing, or breathing difficulty.
Could a tooth be causing the inner gum swelling?
Could the swelling be coming from the tooth rather than the gum? Ask how the examination will change the treatment recommendation.
Frequently asked questions
Why is one small spot swollen?
A trapped irritant, gum pocket, trauma, or infection around one tooth can cause a localized lump.
Will brushing make it worse?
Gentle brushing removes plaque; forceful scrubbing or poking can further traumatize the area.
