Blood comes from gums

Bleeding gums usually reflect inflammation from plaque, but persistent or heavy bleeding needs an examination for gum disease and other causes.

The blood is coming from gum tissue rather than from the tooth itself. Common contributors include plaque-related gingivitis, brushing forcefully, a new flossing routine, a poorly fitting appliance, smoking, and some medicines; a dentist also checks for periodontitis and local infection.

Brush the gumline gently with a soft toothbrush and clean between the teeth daily with floss or interdental brushes. Do not stop cleaning the area because light bleeding can accompany inflamed gums, but arrange a professional examination and cleaning if it continues after careful home care.

Book dental care for bleeding that recurs, spontaneous bleeding, swollen or tender gums, bad breath, loose teeth, or pus. Seek urgent help for bleeding that is heavy or does not settle with firm gauze pressure, or when facial swelling, fever, or difficulty swallowing occurs.

Ask whether the bleeding is gingivitis, periodontitis, an infection, or irritation from a local factor. Ask which cleaning method fits your gum spaces, whether a professional scale is needed, and what changes would require prompt review.
