How to floss properly: a step-by-step guide

Flossing cleans the sides of the teeth where a toothbrush does not reach. Plaque left between teeth is a common cause of decay and gum disease, so cleaning between the teeth once a day is recommended.

How to floss, step by step

• Take about 45 cm of floss and wind most of it around the middle fingers, leaving a few centimetres to work with.
• Hold the floss tight between thumbs and index fingers and ease it between two teeth with a gentle side-to-side motion. Do not snap it onto the gum.
• Curve the floss into a C shape against one tooth and slide it just under the gum line.
• Move it up and down the side of the tooth several times, then do the same on the neighbouring tooth.
• Use a clean section of floss for each gap, and remember the back of the last tooth.

How often should you floss?

Once a day is enough for most people. The time of day matters less than doing it thoroughly. Whether to do it before or after brushing is covered in floss before or after brushing.

My gums bleed when I floss

Bleeding usually means the gums are inflamed from plaque, not that flossing is harming them. With gentle daily flossing it often settles within one to two weeks. If it continues, see bleeding gums when flossing and book a check, as it can be a sign of gum disease.

Floss, interdental brushes or a water flosser?

• Floss or tape suits tight contacts between teeth.
• Interdental brushes clean larger gaps, around bridges and under orthodontic wires, and many people find them easier to use.
• Floss holders help if you have limited hand movement or are flossing a child’s teeth.
• Water flossers are useful around braces and implants, and are a reasonable option if you cannot manage floss.

Your dentist or hygienist can show you which size and tool suits your teeth at a scale and clean appointment. Hardened plaque cannot be removed by flossing; see tartar and dental calculus.
