My gums are bleeding when i floss

Bleeding during flossing often means inflamed gums or cleaning technique problems, but persistent bleeding needs a gum examination.

Plaque trapped between teeth irritates the gingiva and makes its small blood vessels more likely to bleed. Snapping floss into the gum, using a contaminated appliance, or taking medicines that affect clotting can also contribute.

Use clean floss, curve it into a C against each tooth, and move it below the gum edge with light pressure. A correctly sized interdental brush may clean wider spaces more effectively; brush twice daily with fluoride toothpaste.

Book a dental visit if bleeding recurs, gums are swollen, breath smells persistently unpleasant, or teeth feel loose. Seek urgent care for uncontrolled bleeding, facial swelling, fever, or trouble swallowing.

Ask whether you have gingivitis, deeper periodontal pockets, decay between teeth, or a technique problem. Ask which floss or interdental brush size fits each space and whether any medicine or health condition changes your bleeding risk.
