Flossing with braces is different from flossing without them. The wire blocks your usual up-and-down path, and the brackets create new nooks where food and plaque collect. Skipping flossing during treatment leads to white spots on your teeth (a permanent consequence of plaque sitting against enamel), gum inflammation, and longer treatment time if decay shows up. The good news: once you pick a method and practice it a few nights, flossing with braces takes less time than you think.
Why Flossing Matters Even More With Braces
Brackets, bands, and wires give plaque new places to hide that a toothbrush cannot reach. Plaque that sits against your enamel for weeks or months can leave permanent white or brown stains called decalcification, the kind of mark you see on the teeth of patients who did not floss during treatment. Gum inflammation (gingivitis) is also common in braces patients who skip flossing, and inflamed gums actually slow your treatment down because swelling makes it harder for teeth to shift.
Our goal is that on the day your braces come off, your teeth look healthier, not worse. That only happens if you floss daily. For a fuller picture of what good oral care looks like during treatment, see why oral hygiene matters more once you have braces.
What You Need
You only need one of these tools, not all of them. Try a couple and stick with whichever you actually use consistently. The best tool for braces flossing is the one you will do every night.
- Floss threaders. Small plastic loops that help you thread regular floss under your archwire. Inexpensive, slow at first, but get faster with practice. Most patients find a box of 100 at the drugstore for a few dollars.
- Water flosser (such as Waterpik). A device that sprays a thin, pressurized stream of water between teeth and around brackets. Faster than threading, especially helpful for kids or anyone with limited dexterity. More expensive upfront.
- Super floss. Pre-cut strands with three sections: a stiff threader end, a spongy middle for wider gaps, and regular floss. Sold in boxes at any drugstore. A middle-ground option in terms of speed and cost.
- Orthodontic floss picks. Disposable plastic picks designed to slip under braces wire. Fast for a quick clean, but harder to maneuver at the back teeth.
Step-by-Step: How to Floss With Braces Using a Floss Threader
This is the classic method. If you can do this one, you can always fall back on it if your water flosser breaks or you forget to bring it on vacation. Plan for 5 to 10 minutes the first few nights. You will get faster.
- Cut an 18-inch piece of waxed floss. Waxed is important. Unwaxed floss shreds on brackets.
- Thread the floss through the plastic threader. Push one end of the floss through the loop, and pull until the threader is roughly in the middle of your floss.
- Feed the pointed end of the threader up between your archwire and your teeth. Work on one gap at a time. The threader acts like a fishing line, pulling the floss behind it.
- Pull the floss through until you have a workable length on both sides. Grip the floss with both hands, about 4 to 5 inches apart.
- Slide the floss up to your gum line. Curve the floss into a C-shape against one tooth. Move it gently up and down 3 to 4 times.
- Repeat against the adjacent tooth. Same gap, opposite tooth. Up and down against the tooth surface.
- Pull the floss out carefully, back down the way it came. Do not try to pull it through the contact point between teeth; the wire will block it.
- Rethread and move to the next gap. Work your way around your mouth systematically. Do not skip the back molars.
Rinse thoroughly when you are done. Any food debris you dislodged while flossing should be rinsed away, not swallowed.
Using a Water Flosser Instead
If threading is too slow for your schedule, a water flosser is a solid alternative. Fill the reservoir with lukewarm water, set the pressure to medium (start low if you have tender gums), and trace the water stream along your gumline and around each bracket. Aim the tip at the gumline at a slight angle, move slowly, and spend about a second on each tooth surface. The whole process takes about 1 to 2 minutes once you are practiced. Follow-up with regular brushing as usual.
Water flossing does not fully replace string flossing for some patients: your orthodontist or hygienist can tell you at checkups whether your cleaning is effective based on what they see at the gumline. For most braces patients, a water flosser plus good brushing is sufficient.
Common Mistakes to Avoid
- Skipping the back molars. These are the hardest to reach and the most common location for plaque buildup and decay.
- Flossing too hard. Aggressive flossing can damage your gums and even loosen brackets. Firm but gentle is the right pressure.
- Reusing floss segments. As you work around your mouth, shift to a fresh segment of the 18-inch strand so you are not redistributing plaque.
- Only flossing the night before a cleaning. Your hygienist can tell. More importantly, your gums can tell, and the damage from 27 days of not flossing does not undo itself in one night.
- Not rinsing after flossing. Dislodged debris needs to go somewhere other than back into your gum line.
Frequently Asked Questions
How often do I need to floss with braces?
Every day, ideally at night before bed. Your toothbrush cannot reach the tight spaces around brackets and under the wire, so flossing is the only way to remove plaque from those areas. Once a day is the minimum; some patients floss after every meal, which is more than necessary for most cases.
Is a water flosser better than a floss threader?
For most patients, both work well and the best tool is the one you will use consistently. Water flossers are faster and easier to use, but more expensive upfront. Floss threaders are slow at first but cheap and effective once you have practiced. Try one method for a couple of weeks, and switch if you are not keeping up with daily flossing.
What happens if I skip flossing during treatment?
In the short term, your gums will likely become inflamed, red, and prone to bleeding when you brush. In the long term, you can develop permanent white spots on your teeth where plaque sat against the enamel (decalcification), along with decay under or around brackets. None of those outcomes are reversible, so daily flossing is worth the 5 to 10 minutes.
My gums bleed when I floss. Is that normal?
In the first week or two of flossing, some bleeding is common and usually indicates that your gums were already inflamed from plaque buildup. The bleeding should stop within a week or two of daily flossing as the inflammation resolves. If bleeding persists for more than two weeks of consistent flossing, let us know at your next appointment.
Should my kid use a floss threader or a water flosser?
Water flossers are generally easier for kids and teens because they require less dexterity. That said, many kids manage threaders just fine with a little practice. If your kid simply will not floss with a threader, buy the water flosser. Daily flossing is worth the $50 to $100 investment.
