Colgate interdental floss
Dental floss is a thread for cleaning the contact areas between teeth, and the correct technique matters more than the brand printed on the package.
The short answer
Interdental cleaning removes plaque and food from surfaces a toothbrush cannot reach. Floss is useful where teeth contact closely; interdental brushes or water flossers may suit wider spaces, bridges, or braces.
What is the direct answer?
What does this question mean?
Floss can cause bleeding when gums are inflamed or when the thread is snapped into tissue. Fraying, shredding, or repeated catching may indicate rough edges, calculus, an overhanging filling, or a tight contact.
What can you do next?
Guide the floss gently through the contact, curve it around one tooth in a C shape, slide below the gum margin without forcing, then clean the adjacent tooth with a fresh section. Use an interdental brush when it fits without wedging.
When should you seek dental care?
Ask for an examination if bleeding continues, a contact traps food, floss repeatedly tears, or a tooth is painful. A dentist or hygienist can check contacts, fillings, calculus, and gum spaces.
What should you ask the dentist?
Ask which method matches each gap and whether your technique reaches below the contact. Ask whether a filling contour, calculus, or gum pocket is making floss difficult.

Can this be managed at home?
Home measures can reduce irritation temporarily, but persistent or recurring symptoms need assessment.
