Gum swelling after brushing

Gum swelling after brushing often reflects existing inflammation, brushing trauma, or a local irritant rather than the toothbrush creating a new disease.

The gingiva can swell when plaque remains at the gum margin, when a brush is pressed too hard, or when calculus, food, orthodontic hardware, or a rough restoration rubs the tissue.

Use a soft brush with light pressure and small movements at the gumline, and clean between teeth with an appropriate interdental method. Replace a worn brush and have persistent swelling examined for periodontal disease or a local infection.

Seek prompt care for pus, fever, facial swelling, severe pain, a loose tooth, or trouble opening the mouth, swallowing, or breathing. Arrange routine care if swelling continues or repeatedly bleeds.

Ask the dentist to demonstrate the correct pressure and interdental method. Ask whether calculus, a deep gum pocket, decay, or a restoration is contributing to the swelling.
