Bleeding gums when cleaning teeth

Bleeding during brushing or cleaning between teeth often indicates inflamed gum tissue, commonly from plaque along the gumline.

Plaque bacteria irritate the gingiva and can cause redness, swelling, and bleeding. Brushing trauma, gum disease, dental work, smoking, medicines, and medical conditions can also contribute.

Use a soft brush and clean between teeth with floss or an appropriately sized interdental brush. Continue gentle cleaning rather than scrubbing harder or stopping altogether.

Arrange an examination if bleeding persists, occurs spontaneously, or comes with bad breath, recession, loose teeth, or pus. Heavy bleeding that will not stop needs urgent help.

Ask whether the cause is gingivitis, periodontitis, or local irritation, and which interdental tool and technique fit your mouth.
