Gingival erythema causes

Red gums commonly reflect plaque-related inflammation, but irritation, infection, medicines, or systemic illness can also change gum color.

Gingival erythema means the gum tissue looks redder than its usual coral-pink color. The change may be localized around one tooth or spread along the gumline, with swelling, tenderness, bleeding, or ulcers helping narrow the cause.

Brush gently with a soft brush at the gum margin and clean between the teeth daily. Avoid tobacco and stop any new mouth product that clearly irritates the area, while arranging an examination if the redness persists.

Seek prompt care for facial swelling, fever, pus, severe pain, a loose tooth, or trouble swallowing or breathing. A dentist may measure gum pockets, inspect plaque and calculus, test a painful tooth, and check medicines or medical conditions.

Ask whether the redness is gingivitis, periodontitis, trauma, allergy, or a tooth infection. Ask which areas need professional cleaning, whether radiographs or periodontal measurements are needed, and how to monitor healing.
