How to Floss with Braces: Tools, Techniques, and Step-by-Step Instructions

Can You Floss with Braces?

Yes — and you must. Flossing with braces is more challenging than flossing without them, because the archwire runs across all your teeth and prevents you from simply sliding floss down between teeth the normal way. But it is absolutely possible, and there are multiple tools specifically designed to make it easier.

Skipping flossing during braces treatment leads to:

• Plaque buildup around brackets and along the gumline
• Gum inflammation and bleeding — the early signs of gingivitis
• Cavities in the contact areas between teeth, which are the hardest to clean with a toothbrush
• White spot lesions — permanent marks on the enamel surface that appear when braces come off
• Extended treatment time if dental issues require interruption of orthodontic care

The American Association of Orthodontists recommends flossing at least once per day during braces treatment. Many orthodontists recommend after every meal.

How Often Should You Floss with Braces?

At minimum, once per day — ideally before bed so your teeth are clean overnight. If possible, flossing after every meal is better, particularly if you've eaten anything sticky or fibrous. The longer food and plaque sit between your teeth and around your brackets, the more damage they cause.

Flossing Tools for Braces: Which One Is Right for You?

There is no single best tool — the right choice depends on your dexterity, how much time you have, and what feels comfortable. Here's a breakdown of every option

1. Floss Threader — The Classic Method

A floss threader is a small, flexible plastic needle with a loop at one end. You thread regular dental floss through the loop, then use the stiff tip to guide the floss behind the archwire and between two teeth. It's the most widely recommended method because it uses standard floss and gives you full control.

Best for: patients who want thorough cleaning and don't mind taking time

Time required: 10–20 minutes for a full mouth

Step-by-Step: How to Floss with a Floss Threader

1. Cut a piece of waxed dental floss about 18 inches long
2. Thread one end through the loop of the floss threader
3. Insert the stiff tip of the threader under the archwire between two teeth
4. Pull the floss through until you have a few inches on each side of the wire
5. Wrap the ends around your index fingers for control
6. Gently slide the floss down between the two teeth, curving it into a C-shape against one tooth
7. Slide up and down along the side of the tooth, going just under the gumline
8. Repeat on the adjacent tooth surface
9. Pull the floss out — do not try to slide it back under the wire. Remove it and re-thread for the next gap
10. Repeat for every space between teeth

Tip: Use waxed floss — it slides more easily between teeth and is less likely to shred on brackets than unwaxed floss.

2. Orthodontic Floss — Pre-threaded and Ready to Use

Orthodontic floss (sometimes called super floss) comes with a stiff threader end already attached, followed by a spongy section and regular floss. The stiff end threads under the wire, the spongy section cleans around brackets, and the regular floss section cleans between teeth. Brands like Oral-B Super Floss are the most widely available.

Best for: patients who want an all-in-one solution without a separate threader

Time required: 10–15 minutes for a full mouth

Step-by-Step: How to Use Orthodontic Super Floss

1. Hold the stiff end of the super floss
2. Thread it under the archwire between two teeth
3. Use the spongy section to clean around the bracket by moving it back and forth gently
4. Use the regular floss section to slide between the two teeth, curving against each tooth surface
5. Go just under the gumline on each side
6. Pull out and move to the next space

3. Water Flosser — Fastest and Easiest

A water flosser (like Waterpik) uses a pressurized stream of water to flush food particles and plaque from between teeth and around brackets. It does not replace flossing entirely — it cannot remove the sticky plaque film that only physical contact with floss can dislodge — but it is an excellent complement to string flossing and significantly easier to use with braces.

Many orthodontists recommend water flossers as a primary tool for patients who struggle with traditional flossing, or as a daily supplement alongside weekly string flossing.

Best for: patients who find string flossing difficult, patients with limited dexterity, daily maintenance between deeper flossing sessions

Time required: 3–5 minutes for a full mouth

Step-by-Step: How to Use a Water Flosser with Braces

1. Fill the reservoir with lukewarm water
2. Select the orthodontic tip if your device came with one (it has a small brush at the end that helps clean around brackets)
3. Lean over the sink and place the tip in your mouth before turning it on
4. Start on the lowest pressure setting — you can increase once you're comfortable
5. Aim the tip at the gumline at a 90-degree angle and trace along the gumline from tooth to tooth
6. Then aim the tip directly at each bracket, flushing around all four sides
7. Finally, aim between each pair of teeth, holding briefly to flush the contact area
8. Spit water as needed throughout

Tip: Don't aim the tip directly at brackets at full pressure — start gentle to avoid dislodging any weakened brackets.

4. Interdental Brushes — Great for Around Brackets

Interdental brushes (also called proxy brushes or interproximal brushes) are tiny bottle-brush-shaped tools that fit between teeth and around brackets. They are excellent for cleaning the areas immediately around bracket edges where floss can miss. They are not a substitute for flossing between teeth and under the gumline, but they are a valuable addition to your routine.

Best for: cleaning around bracket edges and under wires as a supplement to flossing

Time required: 2–5 minutes

How to Use Interdental Brushes with Braces

1. Choose a size that fits snugly but not forcefully between your teeth and bracket
2. Insert the brush under the wire and around the bracket
3. Move it back and forth gently to dislodge debris
4. Repeat around every bracket and under the wire sections between brackets

Standard floss picks have a small Y-shaped frame with a short section of floss stretched across it. They are convenient for quick use but have a major limitation with braces: the short floss section is fixed, making it very difficult to thread under the archwire. They work best for patients with Invisalign or no braces, but some patients use them for quick touch-ups between meals if they can maneuver them under the wire.

Best for: Invisalign wearers or as a quick backup — not recommended as a primary flossing tool for braces

Which Flossing Method Is Best for Braces?

The best routine for most braces wearers: use a floss threader or super floss for deep cleaning once per day, and supplement with a water flosser for quick daily maintenance.

How to Build a Complete Flossing Routine with Braces

The most effective routine combines flossing with brushing and rinsing into a sequence that covers every surface:

1. Rinse with water to loosen food particles before brushing
2. Brush for 2 minutes with a soft-bristle toothbrush and fluoride toothpaste, angling at 45 degrees to the gumline
3. Floss using your preferred method — threader, super floss, or water flosser
4. Use interdental brushes around brackets if needed
5. Rinse with fluoride mouthwash to reach any remaining areas and strengthen enamel

Common Flossing Mistakes to Avoid with Braces

• Snapping the floss — never snap floss down hard between teeth. Slide it gently to avoid damaging gum tissue.
• Skipping the gumline — the most important area to clean is just under the gumline, where plaque causes the most damage. Make sure you curve the floss against each tooth and dip slightly below the gum.
• Reusing the same section of floss — use a fresh section of floss for each gap. Reusing the same section transfers bacteria from one area to another.
• Rushing — flossing with braces takes longer than without. Budget the time — 10–15 minutes with a threader for the first few weeks, dropping to around 10 minutes once you're practiced.
• Skipping days — one missed day allows plaque to begin hardening into tartar, which cannot be removed by flossing at home.

Frequently Asked Questions

How do you floss with braces?

The most common method is using a floss threader — a small flexible tool that guides regular dental floss under the archwire between teeth. Thread the floss through the loop, insert the stiff tip under the wire, pull the floss through, and slide it between each pair of teeth in a C-shape against each tooth surface. Orthodontic super floss and water flossers are easier alternatives that many patients prefer.

Can you floss with braces using regular floss?

Yes — but you need a floss threader to get regular floss under the archwire. Without a threader, it's nearly impossible to navigate regular floss between teeth when braces are present. Waxed floss is recommended as it slides more easily and is less likely to shred on brackets.

How long does it take to floss with braces?

Using a floss threader takes approximately 10–20 minutes for a full mouth when you're first starting out. With practice, most patients get it down to around 10 minutes. A water flosser takes 3–5 minutes for a complete rinse.

How often should you floss with braces?

At least once per day, ideally before bed. If possible, flossing after every meal is better — especially after eating anything sticky, fibrous, or sugary.

What is the easiest way to floss with braces?

A water flosser is the easiest method — it requires no threading under wires and takes only 3–5 minutes. While it doesn't replace string flossing entirely, it is highly effective for daily maintenance and is especially useful for patients who struggle with manual dexterity or find threading time-consuming.

What happens if you don't floss with braces?

Skipping flossing during braces treatment leads to plaque buildup between teeth and around brackets, gum inflammation, cavities in contact areas, and white spot lesions — permanent enamel marks that become visible when braces are removed. It can also extend treatment time if dental issues require interruption of orthodontic care.

Is a water flosser good enough for braces?

A water flosser is an excellent tool for braces but works best as a complement to string flossing rather than a complete replacement. String floss physically removes the sticky plaque film that water pressure alone cannot dislodge. The best routine combines both: string floss for deep cleaning once daily, and a water flosser for quick supplemental cleaning after meals.
