Bleeding gums is a symptom of

Bleeding gums are commonly a symptom of gingivitis, but periodontitis, local injury, medicines, and systemic problems can also cause them.

Gingivitis is inflammation of the gingiva caused mainly by plaque at the gum line. If inflammation extends deeper, periodontal pockets and loss of supporting bone may develop; bleeding alone cannot distinguish these stages.

Keep the gum line clean with gentle brushing and interdental cleaning, even if light bleeding occurs at first. Have calculus removed professionally and review any new medicine or health change with the appropriate clinician.

Seek dental care for bleeding lasting beyond a brief irritation, recurrent bleeding, bad breath, gum recession, or tooth looseness. Seek medical help for uncontrolled bleeding or bruising in other areas.

Ask what diagnosis best explains the bleeding, whether pocket measurements or radiographs are needed, and how the gums will be reassessed after cleaning. Ask whether a medicine or medical condition changes the plan.
