Flossing is one of the most effective ways to clean the sides of your teeth and just under the gumline, where cavities and gum problems often start. Many people know they should floss but are unsure of technique, or they floss too hard and give up when their gums bleed. Getting the motion right makes it more comfortable and far more likely to become a daily habit.
What you need
Dental floss — waxed or unwaxed is fine; use what you can slide gently between your teeth.
Optional: floss picks or holders if you find them easier, though traditional floss often adapts better to tight contacts.
Clean hands and a mirror while you are learning the technique.
Step-by-step: how to floss correctly
Break off about 45 cm of floss. Wind most of it around one middle finger and the rest around the opposite middle finger, leaving a few centimetres taut between them.
Slide the floss gently between two teeth — do not snap it down onto the gums.
When the floss reaches the gumline, curve it into a C-shape against one tooth and slide it slightly under the gum. Rub gently up and down the side of that tooth.
Move to the neighbouring tooth and repeat the C-shape on the other side of the same gap.
Use a fresh section of floss for each new space so you are not moving bacteria from one gap to another.
Include the back surfaces of your last molars; they are easy to miss.
Tips that help
Floss before or after brushing — the order matters less than doing it consistently once a day. Many people floss at night so the mouth is clean during sleep. If your gums bleed at first, light bleeding can happen when inflammation is present; with gentle daily flossing and good technique, it often improves within a week or two. If bleeding is heavy or does not settle, book a hygiene appointment so we can check for tartar or gum disease.
Habits that make it easier
Keep floss where you will see it — next to the toothbrush or on your pillow for a reminder.
Start with just a few teeth until the motion feels natural, then add more each day.
If string floss is awkward, ask your hygienist about interdental brushes or a water flosser as an addition — they do not replace brushing, but they can help some mouths.
When to see a hygienist
You should still have professional cleans even with excellent home care. Hygienists remove tartar you cannot floss away and spot areas you might be missing. If floss shreds in one spot, if a gap suddenly feels tight, or if pain and bleeding continue, get checked — there may be tartar, a rough filling edge, or gum disease that needs treatment.

FAQ
Q: How often should I floss? A: Once a day is the usual target for cleaning between teeth. Twice is not harmful if you are gentle, but consistency matters more than frequency beyond that.
Q: Should I floss before or after brushing? A: Either is acceptable. Some studies suggest flossing before brushing may help fluoride reach between teeth; the most important thing is that you do both thoroughly.
Q: Can I use a Waterpik instead of floss? A: A water flosser can be a useful addition for many people but it does not remove plaque in exactly the same way as floss or interdental brushes. Ask your hygienist what combination suits your mouth.
Q: My gums bleed every time — is that normal? A: Persistent bleeding needs a dental assessment. Book an appointment so we can check your gums.
