How to Floss With Braces: A Calm, Step-by-Step Guide

Teen carefully flossing around braces

Flossing with braces is slower than flossing without them, but it is very doable. The easiest method for most people is a floss threader (or Superfloss) to get under the main wire, then a gentle C-shape around each tooth. Add a small interdental brush and, if you like, a water flosser, and you have a routine you can finish in a few relaxed minutes each night.

If you have just had your braces fitted and the whole thing feels fiddly, you are not doing it wrong. Everyone starts here. Below we walk you through the tools, the steps, and the small habits that make it easier, so you stay in control of your clean teeth while your smile moves into place.

TL;DR

  • Floss once a day, ideally at night, and thread the floss under the main wire so you can clean between every pair of teeth.
  • A floss threader, Superfloss or floss pick makes the job much easier than plain string.
  • Interdental brushes and water flossers are helpful extras for around brackets, but they work best alongside string floss, not instead of it.
  • Some bleeding in the first week or two is common and is not a reason to stop. Bleeding that carries on is a reason to book a check.
  • Give yourself time at first. A good habit matters more than a perfect technique on day one.

Why flossing is harder (and more important) with braces

Brackets and wires are wonderful at moving teeth. They are also wonderful at catching food. Think of the wire as a fence running across the front of your teeth: floss that would normally slide straight down between two teeth now hits the fence.

That is why plaque builds up so easily around braces. Plaque is the soft, sticky film of bacteria that coats your teeth. Left alone it hardens into tartar, which sticks to teeth like cement and can only be removed by a dental professional. WebMD notes that plaque control around brackets matters so much that some orthodontic patients are advised to have professional cleans every 3 or 4 months rather than the usual 6.

The Queensland Government’s oral health guidance says that good hygiene, including regular brushing and flossing, helps prevent tooth decay during orthodontic treatment. A 2025 narrative review of interdental cleaning aids makes the same point from the research side: plaque collects around brackets and wires, exactly where traditional flossing is often ineffective.

What can happen if you skip it? Mostly the things you would expect: puffy, bleeding gums, white marks or cavities around the brackets, and bad breath. None of this is a failure on your part. It simply means braces need a slightly bigger toolkit.

The tools that make it easier

You do not need all of these. Most people settle on two or three that suit their hands, their schedule and their teeth.

Tool What it does Best for Watch out for
Floss threader A small plastic loop that pulls floss under the wire Beginners, and anyone who wants to use ordinary floss Takes a little practice to feed through
Superfloss or orthodontic floss Floss with a stiff end, a spongy middle and regular floss Quick, one-handed threading Use the thin part for between teeth, the spongy part for under the wire
Floss picks A small handle holding a length of floss Busy days, younger kids, tricky back teeth Cannot easily go under the wire, so they are a back-up
Interdental brush A tiny brush that fits between the wire and the tooth Cleaning around brackets and wider gaps Choose a size that fits without forcing
Water flosser A gentle jet of water that flushes out food Anxious flossers, sore gums, a final rinse An extra tool, not a full replacement

One practical point: the research suggests no single tool wins for everyone. A 2025 review found interdental brushes are strong for mechanical plaque removal in accessible spaces, while water flossers helped reduce bleeding and inflammatory markers. Patient-tailored routines, with brushes for wider spaces and an irrigator for tighter spots, come out best.

How to floss with braces, step by step

Set yourself up first. Stand at a bathroom mirror with good light, and give yourself a few minutes without rushing. Brush before you floss, or floss first and brush after. Either order works, as long as you do both.

Using a floss threader

  1. Cut a length of floss. About 45 cm (roughly 18 inches) gives you room to work. Waxed floss tends to slide past brackets with less shredding.
  2. Thread the floss. Push one end through the loop of the threader, like threading a needle.
  3. Guide it under the wire. Slide the pointed end of the threader between the main wire and your tooth, then pull the floss through until you hold it with a hand on each side.
  4. Floss between the two teeth. Use a gentle back-and-forth motion to ease the floss down between the teeth, never snapping it.
  5. Make a C-shape. Curve the floss around one tooth and glide it up and down the side. Then curve it the other way and clean the neighbouring tooth. Go just under the gumline, where plaque likes to hide.
  6. Come out and move on. Pull the floss out from the front, unthread it, and repeat for the next gap.

The common advice, repeated by Healthline, is that a threader is the most practical way to get floss behind the archwire. It also warns that flossing with braces can take around 10 to 15 minutes at first, compared with 1 or 2 minutes without them. That sounds like a lot. In practice it shrinks quickly as your hands learn the moves.

Using Superfloss

Superfloss skips the threader. Push the stiff end under the wire, pull the length through, then use the spongy section to scrub the sides of each tooth near the gum. It is a good choice if the threader feels clumsy.

Using floss picks on the go

Picks are not a perfect substitute, but a quick pass with a pick after lunch beats no clean at all. Think of them as a back-up for school bags, work bags and sports nights, with proper flossing saved for bedtime.

Add interdental brushes for around the brackets

String floss cleans between teeth. It does not do much for the space between the bracket and the gum, or under the wire edge. That is where a tiny interdental brush earns its place.

Gently slide the brush under the wire, move it back and forth a few times, and repeat around each bracket. Use a size that slides in comfortably. If you have to force it, it is too big.

Interdental brush cleaning around orthodontic brackets

A 2026 systematic review in Frontiers in Oral Health describes interdental brushes as an adjunctive oral hygiene tool for removing plaque from the spaces between teeth. In other words, they add to your toothbrushing and flossing rather than replace them. Many people find them quicker and less awkward than string, so they are the tool that actually gets used.

Where water flossers fit

A water flosser sends a thin, pulsing stream of water along the gumline and around brackets. It flushes out food and can feel soothing, so it is especially popular with people who find manual flossing stressful or uncomfortable.

The important part is knowing its limits. A systematic review of water flossers in orthodontic treatment looked at them as an alternative to traditional tools that have their own limitations. The 2025 review above also treats them as an adjunct. They are very good at removing loose food and calming irritated gums, but plaque is sticky, and sticky film needs a bit of physical contact to lift off.

A simple way to use one:

  • Fill the tank with lukewarm water.
  • Lean over the sink and close your lips enough to stop splashing.
  • Start on the lowest pressure setting.
  • Trace along the gumline, pausing briefly at each tooth and bracket.
  • Finish by brushing and flossing as usual, or do the water flosser last for a final flush.

If you feel anxious about flossing, starting with the water flosser is a gentle way to build confidence. Just keep working towards the threader or interdental brush as well.

A nightly routine you can actually keep

The best flossing method is the one you do every day. Here is a routine that takes about 10 minutes when you are new to it and fewer as you improve.

  1. Rinse. Swish water around your mouth to dislodge loose food.
  2. Floss. Use a threader or Superfloss to clean between every pair of teeth, front and back.
  3. Interdental brush. Clean around each bracket and under the wire.
  4. Brush. Use a soft toothbrush and fluoride toothpaste, angling the bristles toward the gum along the top and bottom of each bracket.
  5. Water flosser (optional). Finish with a pass along the gumline.

For how often, the Cleveland Clinic suggests flossing once a day, at night. If bedtime is the only time you remember, that is the right one to protect. In the morning and after meals, a good brush and a rinse are enough.

What if my gums bleed?

It can be alarming to see pink in the sink, especially when you are being careful. The usual reason is gums that were already a little inflamed from plaque. According to the Cleveland Clinic, bleeding at the start of a new flossing routine often points to existing inflammation, and it tends to settle as the gums get healthier with gentle, regular cleaning.

So the answer is usually to keep going, and be kind to your gums:

  • Use light pressure and a slow, gentle motion.
  • Do not snap the floss down onto the gum.
  • Stay consistent for a couple of weeks.

Book a visit if bleeding does not ease after a couple of weeks of regular cleaning, if your gums look swollen or deep red, if they hurt, or if you notice gums pulling back from your teeth. Those can be signs of gum disease, which is easier to treat early. If that is you, our team can look at your gums and talk through your options, including our gum treatment care.

Our perspective: make it comfortable, and it becomes a habit

At Maxcare Dental, we see many patients who arrive worried that they are not flossing properly with braces. Almost always, the problem is not effort. It is that the routine feels too hard to keep up at 10pm after a long day.

So we do not ask for perfection. We ask for something you can repeat. That might mean a threader on weeknights and a water flosser when your gums are tender. It might mean a floss pick in the school bag for children who are still learning. It might mean sitting down with you at your appointment, showing you where plaque is hiding, and letting you practise while we watch and encourage.

We also know that dental anxiety is real, and that sore, fiddly flossing can make it worse. We explain what we are doing, go at your pace, and tailor advice to your mouth and your language. If something is not working, tell us. There is almost always a different tool that fits better.

Common mistakes to avoid

  • Skipping the wire. Flossing only the gaps you can reach without a threader leaves the most plaque-prone spots untouched.
  • Pressing too hard. Sawing at the gum makes it sore and can put you off flossing altogether.
  • Relying only on a water flosser. It is helpful, but it works best alongside brushing and string floss or brushes.
  • Choosing the wrong brush size. A brush that has to be forced between the wire and tooth can irritate your gums. Pick a smaller size.
  • Saving it for the weekend. A few minutes each day beats a long session once a week.
  • Giving up when it feels slow. The slowness is temporary. Your hands will get faster.

Flossing with braces for kids and teens

Young children often need a hand, and teenagers often need a nudge. A few things help:

  • Make it part of bedtime, right after brushing, so it becomes automatic.
  • Let them choose their tools. A coloured floss pick or a water flosser can feel more fun than a threader.
  • Check in for the first few weeks. A parent standing nearby with a torch makes it easier to see the back teeth.
  • Ask your dentist to demonstrate. Children often take more notice of a demonstration than a reminder from home.

If your child is considering treatment and you are comparing options, our guide to Invisalign and braces in NZ explains how each affects daily cleaning. Removable aligners come out for brushing and flossing, so the routine looks different.

When braces come off

Good habits now pay off later. Once your braces are removed, you may notice paler patches or stained areas where plaque sat for a while. If you want to brighten your smile afterwards, read what dentists do about whitening after braces before you start. Keep flossing daily once the hardware is gone, because teeth and gums stay healthiest with the same routine you built during treatment.

FAQ

Are you supposed to floss with braces?

Yes. Braces make it easier for plaque and food to collect, and brushing alone cannot clean between the teeth or reliably under the wire. Flossing once a day, ideally at night, helps protect your teeth and gums throughout treatment.

What is the easiest way to floss with braces?

For most people, it is a floss threader or Superfloss. Either one gets the floss under the main wire without a struggle. Pair it with a small interdental brush for around the brackets, and a water flosser if you like the extra comfort.

What happens if I do not floss while wearing braces?

Plaque builds up around the brackets and between your teeth. That can lead to bleeding, swollen gums, bad breath and, over time, cavities or white marks that remain after the braces come off. A professional clean can remove hardened tartar, but daily home care is what prevents it building up.

Is a water flosser enough on its own?

Not usually. Water flossers are excellent for flushing out food and are gentle for sensitive or anxious patients. Research still treats them as an addition to mechanical cleaning with brushing, string floss or interdental brushes, not a full replacement.

How long does it take to floss with braces?

At the start, it can take 10 to 15 minutes, according to Healthline. With practice and the right tools, most people get much quicker. If it feels too long, ask your dentist to review your technique and suggest a simpler set-up.
