The short answer
Bleeding during flossing most often reflects inflamed gum tissue from plaque at the gum margin, but technique, calculus, infection, and medical factors can also contribute.
What is the direct answer?
What does this question mean?
Healthy gingiva fits closely around the teeth. Plaque bacteria can trigger gingival inflammation, making the tissue swollen and prone to bleeding when floss passes through the contact area; snapping floss into the gum can also injure it. Use clean floss or an interdental brush gently below the contact point and curve it around each tooth without forcing it into the tissue. Brush with a soft brush and arrange a cleaning if hardened calculus or crowded spaces make home cleaning difficult.
What can you do next?
Book a dental examination if bleeding persists, is heavy, occurs without cleaning, or comes with swelling, pus, bad breath, loose teeth, or pain. Mention easy bruising, bleeding elsewhere, and medicines that affect clotting.
When should you seek dental care?
Ask whether the bleeding is from gingivitis, periodontitis, trauma, calculus, or another cause. Ask which interdental size and technique fit your contacts and whether a gum measurement or radiograph is needed.
Frequently asked questions
Should I stop flossing when my gums bleed?
Do not abandon cleaning altogether; use gentle technique and arrange an examination to identify why the tissue bleeds.
Can flossing cause bleeding in healthy gums?
Aggressive snapping or forcing floss can traumatize tissue, but repeated bleeding should not be assumed to be technique alone.
