Causes of gingival swelling
Gingival swelling can result from plaque-related inflammation, food or appliance irritation, infection, hormonal changes, medicines, or a lesion.
The short answer
Gingival swelling means the gum tissue has increased in volume around one tooth, several teeth, or the whole mouth. The pattern, color, bleeding, pain, pocket depth, dental history, and medicines help distinguish local irritation from a wider oral or medical cause.
How can gentle cleaning help when a gum is swollen?
Rinse away trapped food, use a soft brush, and clean gently between the teeth without cutting into the tissue. A dentist may remove calculus, adjust an irritating restoration or appliance, drain a localized abscess, or investigate a medication and health history.
When should persistent or localised gum swelling be checked?
Arrange a dental assessment for swelling that persists, returns, or is confined to one tooth. Seek urgent care for rapidly spreading swelling, fever, facial swelling, or difficulty opening the mouth, swallowing, or breathing.
Which part of the tooth and gum should the dentist examine?
Ask whether the swelling is in the gingiva, a periodontal pocket, or the root area. Ask what examination or radiograph is needed and whether a medicine, restoration, or oral habit could be contributing.
