Flossing with braces is slower than flossing without them, and the reason is simple: the archwire runs across every tooth, so ordinary floss cannot drop straight down between them. Once you know how to get the floss under the wire, the rest is the same technique you already use. Here is how to floss with braces step by step, the tools that make it faster, and what the orthodontists at Bernstein Orthodontics see when Santa Rosa and Windsor patients skip it.
Key Takeaways
- Floss once a day with braces, at night, after brushing.
- A floss threader or an orthodontic floss with a stiff end gets the floss under the wire; a water flosser is a good addition, not a replacement.
- Curve the floss in a C shape against each tooth and slide it gently below the gumline.
- Flossing may take longer at first because threading under the wire is unfamiliar. With practice, many people find the routine becomes quicker and easier. The first two weeks take ten minutes; by the end of the first month, it takes three.
- Bleeding gums mean floss more, not less. Persistent bleeding, white spots, or swelling need a call to the office.
Why flossing matters more with braces on
Brackets and wires give plaque more places to sit, and the spots they protect best are the ones a toothbrush cannot reach: the sides of each tooth, and the gumline behind the wire. Left alone, plaque there does two things. It irritates the gums, which swell and bleed and can grow over the edges of the brackets, and it dissolves enamel, leaving the chalky white squares around each bracket that show up the day braces come off. The American Dental Association notes that food and plaque trapped around braces raise the risk of both decay and gum disease, and the Cleveland Clinic puts flossing alongside brushing as the daily minimum during treatment.
The practical point is that braces do not cause any of this. Plaque does, and flossing is the only routine that removes it from between the teeth. A patient who flosses through treatment ends with clean, even enamel and healthy gums; a patient who does not can end with straight teeth that carry permanent marks.
What you need
| Tool | What it does | Best for |
|---|---|---|
| Floss threader | A stiff plastic loop that pulls ordinary floss under the archwire | Anyone; the least expensive option |
| Orthodontic floss (stiff-tipped) | Floss with a firm end that threads itself under the wire, and a spongy middle that cleans around brackets | Patients who find threaders fiddly |
| Interdental brushes | Small cone brushes that clean between brackets and under the wire | Quick daytime cleaning; do not replace floss between teeth |
| Water flosser | A jet of water that flushes food and loose plaque from around brackets | An addition for anyone; especially useful after meals |
| Floss picks made for braces | Picks with a slim, angled head that fits under the wire | Travel and school bags |
Any of the first two gets the job done. The rest speed things up. The ADA’s flossing guide covers technique without braces, and everything below is that technique plus one step.
How to floss with braces step by step
- Brush first. Two minutes with a soft brush, angled at the gumline and around every bracket, so the floss is working on clean surfaces. The practice’s oral hygiene with braces guide covers brushing in detail.
- Cut about eighteen inches of floss. Waxed floss slides past brackets more easily than unwaxed and is less likely to shred on a wire.
- Thread under the wire. With a floss threader, pass the floss through the loop, push the stiff end of the threader under the archwire between two teeth, and pull it through so the floss is behind the wire. With stiff-tipped orthodontic floss, push the firm end under the wire directly.
- Wrap and curve. Wind the ends around your middle fingers, pinch a short section between thumb and forefinger, and slide it between the two teeth. Curve it into a C shape against one tooth.
- Clean below the gumline. Slide the floss gently up and down along the side of the tooth, going just under the gum edge. Then curve it against the neighboring tooth and repeat. Do not snap it down.
- Pull out and move on. Pull the floss out from the side rather than up through the wire, rethread at the next gap, and use a fresh section of floss.
- Finish with a rinse. Water is enough. A fluoride mouthwash at night adds protection for enamel around brackets.
- Check in a mirror. Look for anything left around the brackets and along the gumline, and go back with an interdental brush if needed.
The whole process covers every gap in both arches, upper and lower. Many patients find it easiest to work in the same order every night so nothing is missed.
Making it faster
The first week feels slow because threading is new. Three things shorten it. Stand at a mirror with good light rather than flossing by feel. Keep the threader and floss together in one spot in the bathroom so there is no hunting. And use stiff-tipped orthodontic floss for the front teeth, where the wire is easiest to reach, saving the threader for the molars. Most Santa Rosa and Windsor patients report that by the end of the first month, flossing takes about three minutes, roughly the time it takes without braces plus the threading.
A water flosser is the other time saver, and it is worth being clear about what it does and does not do. It is excellent at flushing food and loose plaque from around brackets and under the wire, which is why many patients use it after lunch at school or work. It does not scrape the film of plaque off the sides of the teeth the way floss does, so it is an addition to the routine rather than a substitute. The practice’s braces cleaning tips for beginners cover how to combine the two.
Signs you need to change something
Gums that bleed a little in the first week of flossing are normal; they are inflamed from the plaque that was there before, and they settle within a week or two of daily flossing. Gums that still bleed after two weeks, or that look puffy and red around the brackets, mean plaque is being left behind somewhere, usually at the back molars. White, chalky patches around a bracket are early enamel damage and need to be mentioned at the next adjustment so fluoride treatment can start. And a wire that keeps shredding floss has a rough spot that the office can smooth in a minute; call (707) 575-0600 for Santa Rosa or (707) 836-8360 for Windsor.
The Cleveland Clinic explains what happens to gums that stay inflamed over time, and MedlinePlus has a general overview of why orthodontic treatment is worth protecting. Neither outcome is common in patients who floss nightly.
What Bernstein Orthodontics does to help
Every patient at the practice’s two offices gets a hygiene kit and a demonstration at the fitting visit, and hygiene is checked at every adjustment. The self-ligating Pitts21 and Clear21 brackets used here have no elastic ties, which removes one of the places plaque likes to collect and makes the sides of the brackets easier to floss around. Patients who are struggling can book a short hygiene refresher between adjustments at no charge, and for a teenager who will not floss no matter what, Invisalign Teen is sometimes the more realistic choice; the free consult is where that conversation happens.
Frequently asked questions
How often should I floss with braces?
Once a day, at night after brushing. Twice is better after a sticky or seedy meal, but a thorough nightly floss is the minimum that keeps gums and enamel healthy.
Can I use regular floss with braces?
Yes, with a floss threader to get it under the wire. Waxed floss is easier than unwaxed because it slides past brackets without shredding.
Is a water flosser enough on its own?
No. It flushes food and loose debris well, but it does not scrape plaque off the sides of the teeth. Use it in addition to floss, not instead of it.
Why do my gums bleed when I floss with braces?
Because they are inflamed by plaque that was sitting there. Daily flossing removes the cause, and bleeding usually stops within one to two weeks. If it continues, plaque is being missed somewhere; ask for a check at your next visit.
What are the white marks around brackets?
Early enamel demineralization from plaque left around the bracket. Caught early, it can be halted with fluoride and better cleaning; left alone it becomes a permanent white spot when braces come off.
How long does flossing with braces take?
About ten minutes in the first week, dropping to around three minutes once threading becomes automatic, usually within a month.
Can I floss with braces if I have a permanent retainer too?
Yes. A permanent/bonded retainer also requires cleaning around and under the wire. Depending on the retainer design, a floss threader, interdental brush, or water flosser may help. Your dentist or orthodontist can show you the technique. The bonded wire behind the lower front teeth is threaded under exactly the same way, and it stays after braces come off, so the skill keeps paying off. See the retainers page.
What if floss keeps getting stuck or shredding?
A rough spot on a bracket or wire, or a tight contact between two teeth. Try waxed floss first; if it still shreds in the same place, the office can smooth the spot at a short visit.
Are interdental brushes a substitute for floss?
No. They are excellent for cleaning around brackets and under the wire, and quick to use during the day, but they do not reach between the tight contact of two teeth the way floss does.
Does flossing get easier with self-ligating braces?
Somewhat. Brackets without elastic ties, such as the Pitts21 and Clear21 systems used at Bernstein Orthodontics, have fewer nooks for plaque and are simpler to clean around, though the wire still has to be threaded under.
