What is the direct answer?
Gentle flossing cleans plaque between teeth and under the gum edge without cutting into healthy gum tissue.
What does this question mean?
Dental floss is a flexible filament that passes through the contact between teeth and wipes their side surfaces. Bleeding during early cleaning often reflects inflamed gingiva, while forceful snapping can bruise the gum margin.
What can you do next?
Use a clean section of floss, guide it through the contact with a sawing motion, curve it into a C against one tooth, and move it up and down below the gum edge. Repeat against the neighbouring tooth and use an interdental brush when the spaces are too wide for floss.
When should you seek dental care?
Book an examination if bleeding continues despite careful daily cleaning, or if the gums are swollen, tender, receding, or producing pus. A dentist can check plaque, calculus, gum pockets, cavities, and a filling or crown that traps food.
What should you ask the dentist?
Ask which interdental method fits each gap and whether your technique is traumatizing the gum. Ask whether professional debridement, a filling adjustment, or periodontal treatment is needed for bleeding that does not settle.
Frequently asked questions
Should I stop flossing if my gums bleed?
Use a gentler technique and continue cleaning unless a clinician gives different advice, then arrange an examination if bleeding persists.
What if floss keeps shredding?
A rough filling edge, tight contact, calculus, or damaged floss may be responsible and should be checked.
