Floss cannot drop between two teeth when an archwire, a bonded retainer wire or the span of a bridge sits in the way, so you need a tool that gets it under the obstacle: a flosser built for braces, a loop threader for the floss you already have, or a floss with its own stiff end. We compared six of them, read why the most-named one is drawing complaints this year, and sorted them by appliance and by gap, because the right tool for braces with room under the wire is not the right one for crowded teeth, a bonded retainer or a bridge. In 7 of the first 20 threads we read, a commenter’s tool failed on tight or crowded teeth and they switched, so the page is sorted to match the tool to the gap; expect to end up owning two. If you are choosing a water flosser as well, our best water flosser for braces page covers that; this page is about string.
Evidence Receipt
How we researched this page: we read the guidance pages of the American Association of Orthodontists and the American Dental Association, the Cochrane review of cleaning between teeth, a randomized trial that tested super floss in braces patients, and two orthodontic papers on bonded retainers. We read 53 Reddit threads in full, 954 comments: 31 from r/braces, 16 from r/DentalHygiene, two from r/askdentists and one each from r/orthodontics, r/Dentists, r/adhdwomen and r/Dentalimplant. For ten candidates we read the Amazon listing’s seller and rating pool, and we read Oral-B’s own product page. What that reading found:
- Cleaning between the teeth helps the gums; the evidence is low-certainty and mostly not about braces. Cochrane’s 2019 review of 35 trials in adults found that floss or interdental brushes added to brushing may reduce gingivitis, plaque or both, with interdental brushes possibly better than floss and oral irrigators possibly reducing gingivitis at one month; it excluded studies where most participants wore orthodontic appliances.
- In one supervised cleaning, super floss and a water flosser removed about the same plaque in braces patients. A 2022 randomized split-mouth trial in 34 young adults with fixed braces, funded by a Saudi university, measured plaque before and immediately after one cleaning: scores fell from 0.56 to 0.13 with Oral-B Super Floss and from 0.61 to 0.13 with a Waterpik on the other side of the mouth, with no statistically significant difference overall and a larger effect for the water flosser on the back surface of the molars. It measured a single cleaning, not weeks of use, and the strand it tested predates the 2026 complaints described below.
- Bonded retainers collect calculus. A 2019 review of fixed retainers concludes that “bonded fixed retainers complicate maintaining oral hygiene”, and a five-year study comparing 48 people with a fixed lower retainer against 48 treated without one (and 48 never treated) found significantly more calculus in the retainer group, with no significant difference in gum recession.
- The orthodontists’ association says floss every day, with the tool your care team recommends. The AAO’s page on bleeding gums with braces says persistent bleeding “should not be considered a normal part of treatment”, that in most cases you should not stop cleaning an area because of a small amount of bleeding, and that “you may need a floss threader, orthodontic flosser, or another tool your dental care team recommends”; it lists an interdental brush and a water flosser under additional tools. Its between-visits page asks for flossing at least once a day.
- The ADA lists water flossers among the tools and says they can help with braces and bridges. Its consumer site says people with braces, bridges and other dental work “may find that a water flosser helps them reach every nook and cranny”, in a list of cleaning tools that starts with string floss, and points readers to products with its Seal of Acceptance (MouthHealthy).
Which Tool for Which Mouth
Start with what your orthodontist sent you home with: several commenters’ best tool was the one in their starter kit, and the AAO’s first advice is to ask your care team. Then buy for the gap that tool does not handle.
Braces with room under the wire. Every gap has a wire across it, so a loop threader means threading twenty-odd times a night. The orthodontic flosser skips that: a thin flat arm carries the floss under the archwire in one move. Platypus is the one commenters name, and one orthodontic practice’s product page says of it, “we highly recommend this tool” (Synergi Orthodontic Specialists).
Braces with crowded or tight teeth. The thread we read most often said the gap decides the tool, not the brand: in 7 of the first 20 threads we read a commenter’s tool failed on tight or crowded teeth and they switched, usually to a threader with waxed or smooth floss, sometimes to Super Floss on the tight gaps only. “During treatment it will most likely change what type of floss you can use, as some gaps widen and some close”, one r/braces commenter wrote. Expect to own two tools. Power chains do not rule out the flosser: “I have powerchains and I use a generic brand of Platypus flossers.”
A bonded (permanent) retainer. One wire, usually glued behind the lower front teeth, and the gaps under it are tight. Commenters with retainers say a soft loop buckles or hurts (“I tried passing the floss threader between the gum and tooth and it hurts because I think it’s too thick”, one r/braces poster wrote just after their braces came off), so this is where a firmer threader (BridgeAid) or a threader floss (GUM EasyThread, or Super Floss) earns its place. A flaired hygienist on r/DentalHygiene: “BRIDGE AID threaders. They are much more firm. I even used it under someone’s permanent retainer yesterday and he told me no one has ever been able to get them flossed before.” The section on retainers below has the technique tips.
A bridge. Nothing can drop between the joined crowns, so the floss has to be fed under the span and drawn along the underside. Threaders and threader floss both work; commenters with tight bridges report that thick tips will not pass and that “name brand floss threaders are made of a less flimsy plastic than generic ones”. A bridge you cannot get anything under is a question for your dentist, not a reason to buy a fourth tool; the section on bridges below says why. Our bridge-vs-implant comparison covers the cleaning difference between the two.
Wide gaps and gum recession. The spongy middle of a threader floss fills a space a thin strand does not. Cochrane’s review found interdental brushes may do more for the gums than floss where they fit without trauma, so for a wide gap with no appliance across it an interdental brush is the evidence-backed first try; our best dental floss page covers expanding and tape flosses for people without appliances.
Platypus Orthodontic Flossers: Editor’s Pick
Platypus Orthodontic Flossers for Braces, 30 Count
Best for: Braces with room under the wire: a one-piece flosser, no threading
- Flat arm slides under the archwire; no threading
- 30 flossers, about 27 cents each
- Sold by Platypus, shipped by Amazon; listing first available 2008
- Larger packs share the rating pool

Why We Recommend It
The case for the Platypus is time. With a threader you load the floss, feed the loop under the wire, pull, floss, pull it back out, and repeat for every gap; with the Platypus the floss is already held in a Y-shaped head whose thin side passes under the archwire, so each gap takes one motion. It is the second most-named brand in the 53 threads we read, 84 commenters across 27 threads, behind only Super Floss, and one orthodontic practice’s product page says “we highly recommend this tool”. “They’re the only ones that still allow you do the proper C shape floss technique with braces.” one r/braces commenter wrote; another: “Two years of treatment and my hygienist said there was no problem.” Several commenters use it by day and string floss or Super Floss at night for the gaps it cannot reach. It costs about $8 for 30, sold by the maker and shipped by Amazon, and holds 4.7 stars across 31,959 ratings, a pool shared with larger packs of the same flosser. The newest 50 reviews average 4.2, a smaller dip than most of the ten listings we read.
Key Features
- Y-shaped head: the thin, flat arm goes under the wire, the thicker arm holds the floss taut
- 30 to a pack; packs of 2 to 8 on the same listing
- Platypus’s listing says “Floss Teeth in Under Two Minutes” and that users are “21X more likely to floss daily”; both are the maker’s claims, with no study we could read
Who It’s Best For
Teens and adults in full braces who will floss every night if it takes a few minutes and will not if it takes ten. Anyone whose starter kit did not include one and whose wire sits clear of the teeth.
Potential Downsides
The arm has to fit between your wire and your tooth. Reddit’s complaints come in five kinds: “if your teeth are really close together/crowded it may be a little tougher to get it behind the bands”; “they don’t fit under the wire as seamlessly as they’re supposed to”; “I broke a bracket off using these”; “the platypus floss keeps bending my wires”; and the cleaning complaint, “they don’t get down far enough or wrap the tooth”. Amazon’s newest reviews add that the string “stretches and breaks after using on a couple teeth” and, for one buyer, that they were “Too large to fit behind my braces.” If the arm does not fit, stop pushing: that is what the threaders below are for. At about 27 cents a flosser it has the highest price per use on this page.

GUM EEZ-Thru Floss Threaders: Best for Small Gaps
GUM EEZ-Thru Floss Threaders, 25 Count
Best for: Threading your own floss through tight spaces; the loop one bonded-retainer thread found fits small gaps best
- 25 flexible nylon loop threaders, reusable
- Works with any floss; plastic carry case included
- Sold by Amazon; packs of 2 and 6 share the pool
- Newest 50 reviews average 4.4 against 4.7 lifetime
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
A loop threader is a plastic needle: you pass a length of floss through the loop, feed the tip under the wire or bridge, and pull the floss through behind it. It works with the floss you already like, which matters if you have found one that does not shred on your brackets, and a threader lasts many sessions. GUM’s is sold by Amazon itself, and in an r/orthodontics thread about a bonded retainer a commenter who had tried both found “the GUM brand ones fit more easily through small spaces, but the Dentek ones are cheaper”. It is also the threader an r/braces commenter with crowded teeth settled on when Super Floss would not fit: “Personally, I use GUM Eez-Thru Floss Threaders (100 pack) with any type of dental floss i have lying around.” Pair it with waxed or smooth floss; “Any silk/rubbery floss IMO. Anything else is awful and shreds.” one commenter wrote. Its newest 50 reviews average 4.4 against 4.7 lifetime, a smaller dip than DenTek’s loop (4.2 against 4.7).
Key Features
- Flexible nylon loop threaders, per the listing
- 25 per pack, in a plastic carry case
- Fits any floss, waxed or unwaxed, tape or thread
- Sold by Amazon.com, 4.7 stars across 10,469 ratings (the 2-pack and 6-pack share the pool)
Who It’s Best For
People with a bridge, an implant bridge or a bonded retainer, where there are only a few gaps to thread each night. Braces wearers who have found the orthodontic flossers do not fit their wire.
Potential Downsides
With full braces it is slow and two-handed, which is the whole reason the Platypus exists. At about 28 cents a threader it is the dearest loop threader per unit here, though each is reused. Two recent reviewers say the loop gets stuck in the wire (“they always get stuck and you have to use scissors”) or is too flimsy to push under a tight bridge; the BridgeAid below is the firmer alternative for that case.

DenTek Floss Threaders: Best Multipack
DenTek Floss Threaders, 50 Count
Best for: Households with more than one braces wearer, or anyone who loses threaders
- 50 loop threaders with a case, about 14 cents each
- Takes any floss
- Sold by a third-party seller, shipped by Amazon
- Larger packs share the rating pool
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Same kind of tool as the GUM, twice the count for the same $7, and 4.7 stars across 14,952 ratings. Threaders get lost, dropped in the sink and carried off in school bags, so for a family with braces the 50-pack is the practical buy. The r/braces poster who started the biggest thread we read ended up here: “I got the dentek floss threader and they are great with some simple floss, highly recommend”. The newest 50 reviews average 4.2 against 4.7, in line with the category.
Key Features
- 50 flexible loop threaders in a case, per the listing
- Fits any floss
- Sold by VerSure, shipped by Amazon; 150-count and multipack options share the listing
Who It’s Best For
Two or more braces wearers in one house, or one person who wants a threader in every bag.
Potential Downsides
Three of the newest 50 reviews say the tip is too thick for a permanent retainer or for tight teeth; one called it “more like fishing line than floss”. For a retainer, look at the BridgeAid. It is sold by a third-party seller rather than Amazon, so check the seller line if the price looks off.

Bridge Aid Floss Threaders: Best Firm Threader
Bridge Aid Floss Threaders, 5 Packs of 10
Best for: A bridge or a bonded retainer that folds a soft threader
- Shorter, firmer threaders in five packs of ten
- About 12 cents each, the lowest here
- Sold by a third-party seller, shipped by Amazon
- Newest 50 reviews average 4.6, the same as its lifetime rating
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
BridgeAid threaders are shorter and stiffer than the GUM and DenTek loops, and that is the point: where a soft loop folds, this one passes. Two flaired hygienists in an r/DentalHygiene thread recommend it. One had used it under a patient’s bonded retainer the day before: “BRIDGE AID threaders. They are much more firm. I even used it under someone’s permanent retainer yesterday and he told me no one has ever been able to get them flossed before.” The other draws a line: “I highly recommend bridge aid instead of retainer threaders for bridges and braces. Only the retainer threaders for perm retainers.” So the strongest professional case is for bridges and braces; for a bonded retainer, one hygienist’s success and one r/braces commenter’s “The one my ortho gave me worked the best, BridgeAid” are what we have. Its Amazon record is the steadiest on this page: the newest 50 written reviews average 4.6, exactly its lifetime figure, on a listing first available in 2013, and at about 12 cents a threader it is the cheapest unit here.
Key Features
- Firm threader, shorter than the standard loop
- 50 to a box, in five packs of ten
- Sold by FireflySupply, shipped by Amazon
Who It’s Best For
Bridge owners whose softer threaders keep buckling, braces wearers who thread rather than use a flosser, and bonded-retainer owners who want to try the firmer tool.
Potential Downsides
Firm cuts both ways. An unflaired commenter in the same hygienists’ thread: “Bridge aids are the stiffest but also thick and uncomfortable to some patients.” The few low Amazon reviews split between “Too thin and flexible” and “Too short and thick, hard to get under bridge”, and one from 2024 complained of excess plastic on some threaders. The listing is a third-party seller’s, and the five small envelopes are easy to misplace.

GUM EasyThread Threader Floss: Best All-in-One
GUM EasyThread Threader Floss, 50 Uses
Best for: Bridges, implant bridges and bonded retainers, when you want threader and floss in one strand
- Expanding floss on a spool; each of the 50 uses has a stiff threader section built in
- Pull out to the green threader, cut in its middle, feed it under, floss
- Sold by Amazon; a 3-pack shares the pool
- About 20 cents a use
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
This is the Super Floss idea in a spool. GUM’s listing describes it: pull the floss out of the rewindable dispenser until you reach a stiff green floss threader, cut the floss in the middle of the threader, and you have a strand with a rigid end to feed under the appliance and a soft expanding length to clean with; each roll gives 50 uses. Nothing to load and nothing to lose. Its newest 50 Amazon reviews name bridges, implant bridges or permanent retainers eleven times (“Perfect for bridges”; “It makes my flossing with a permanent retainer simply easier.”), and a flaired hygienist on r/DentalHygiene names it in three threads, once to a poster asking what to use under a bridge: “I’m partial to GUM EasyThread floss myself. It combines the floss and the threader into one. (Oral B’s Superfloss is a similar concept.) GUM also makes regular floss threaders if you like having them separate.” It is sold by Amazon at about $10 for 50 uses.
Key Features
- Expanding floss with a built-in rigid threader section at each use, 50 uses a roll, per the listing
- Rewindable dispenser
- Sold by Amazon.com, 4.4 stars across 1,941 ratings; the 3-pack shares the pool
Who It’s Best For
People with a bridge or a bonded retainer who want one product in the drawer. Anyone who bought Super Floss for the spongy middle and wants the same idea from another maker.
Potential Downsides
Its newest 50 reviews average 3.8 against 4.4, inside the range we saw across this category but worth reading: the expanding floss shreds on some tight contacts, two reviewers found the stiff end “Too thick to fit under bridge”, and because it comes on a spool “The stiff part of the floss is always curved”, as a 2025 reviewer put it. One reviewer’s bathroom steam softened the wax in the dispenser. It is the lowest-rated card on this page and the least-reviewed, with 50 written reviews spread across seventeen months, and its forum record is thin: that one hygienist for, and two commenters against (“It has a good hard threading tip, but the floss itself is too thick”; for tight teeth under a bonded retainer, “Neither of these work well for tight teeth with permanent retainers.”).

Oral-B Super Floss: The Most-Named Strand, With a 2026 Caution
Oral-B Super Floss Pre-Cut Strands, 100 Strands
Best for: The most-named strand in the threads we read, if the box you get matches the one people mean
- Pre-cut strand: stiff threader end, spongy middle, plain floss
- 100 strands, about 7 cents each; sold by Amazon
- The strand tested in the 2022 braces trial, before the 2026 complaints
- Newest 50 reviews 3.6 against 4.5 lifetime; buyers report a change
(Affiliate link) · Free shipping on eligible Prime items
Why It Is Here
Super Floss is the most-named product in the 53 threads we read, 93 commenters across 43 of them, and the one new braces patients say they were handed. Two flaired hygienists on r/DentalHygiene use or suggest it (“I personally use superfloss.”; “use superfloss or a flossthreader if you need something more sturdy”), and the orthodontic practice page above calls it “great for braces or bonded retainers”. Each strand has a stiff end to feed under the appliance, a spongy length to scrub around it, and plain floss for the rest of the gap, so it does what a threader plus floss does in one piece, at about 7 cents a strand from Amazon itself. The praise is specific: “not once has it shredded up on me. It has a skinny end thats similar to normal floss and a thicker end”; “I feel like I get more range of motion since there’s more string” from a commenter who prefers it to the Platypus; and from a bonded-retainer wearer on r/adhdwomen, “It’s precut and one side is pointed so it kind of self threads. It’s made flossing beneath my permanent retainer so much easier”.
Key Features
- Three sections in one pre-cut strand: stiffened end, spongy floss, regular floss, per Oral-B
- 100 strands in a box; mint, per the listing (a 50-strand box sits on a separate listing)
- Sold by Amazon.com, 4.5 stars across 28,906 ratings on this listing alone
Who It’s Best For
People whose orthodontist or hygienist handed them a box and who have a method that works. Anyone with a bridge or bonded retainer who wants the spongy section as well as the threader.
Potential Downsides
It carries no badge and sits outside our top picks because its newest reviews describe a change in the product, not a matter of taste. On this listing the newest 50 written reviews average 3.6 against the 4.5 lifetime figure, with buyers saying “The plastic, threader part of these are way too flimsy” and “I prefer the ones that used to be in individual packets with a slightly thicker threaded.” On the 50-strand listing, which we have not linked, the newest 50 average 3.1 against 4.4, with 23 of 50 at two stars or below, and the complaints add length: “It is only 13 inches”, “There is not enough to wrap around your fingers.” One reviewer there, who describes herself as a retired registered dental hygienist, wrote on November 1 that “This is NOT the Super Floss you’ve come to know and love!!!”. Oral-B’s own product page shows 2.6 out of 5 across 281 reviews, with 43% of reviewers recommending it, and its most-helpful reviews from a decade ago already complain that the threader lost its stiffness; the 2026 wave adds the packaging and, on the smaller box, the length. Reddit’s complaints are older and different in kind: fibres left on brackets (“My dentist was literally pulling threads out of my gums at my cleaning last week”), sore gums (“the force from pushing has damaged my gums and I bled for an hour”), tight teeth (“don’t recommend the superfloss ones for really tight gaps”), and a soft threader end (“the threader on the SuperFloss just isn’t firm enough to force between my teeth”), with a flaired hygienist agreeing: “Sometimes super floss has a flimsy end so floss threaders where you have to feed the floss through works better than super floss for tight areas.” One r/braces commenter in August 2026 said it “used to work better years ago”; nobody in the 53 threads we read mentions the shorter strands, and the one packaging complaint, from February 2026, calls the design “idiotic” without saying it changed. If your current box works, nothing here should change that; if a new box does not, the GUM EasyThread above is the same idea from another maker, with its own shredding complaints. We will re-read both listings in January.

Other Products Readers Compare
Plackers OrthoPick is the braces pick that appears beside Super Floss in Google’s shopping cards for this search. We read its newest 50 Amazon reviews and 19 of them are at two stars or below, with one complaint for fourteen months: the flat pick is too thick or too wide to fit under the archwire (“They barely fit under my wire”, “much too thick and broad”, “they do not fit between the brackets”), and one buyer’s picks were “getting stuck between my teeth, had to cut them out with scissors”. Its lifetime rating is 4.6 across 15,238; its recent one is 3.5. Two r/braces commenters like it. Not linked. GRIN Braces Flosser draws the same complaint plus worse: “a round bump on the skinny piece that literally locks under the wires and gets stuck. my wires were bending just by trying to use them.”, wrote one buyer in September; another says “these flossers can cause lots of damage to the braces”. Not linked. Fremouth Orthodontic Flossers are the generic Platypus at about 7 cents each, and two r/braces commenters named them: “The platypus brand ones are probably the most expensive ones on Amazon. I use the Fremouth branded ones which have more per package and costs less.” and “they’re only $10 for a pack of 100”. The orthodontic practice above recommends them too. We have not carded them because the brand has no record beyond its listing, Amazon’s newest reviews report 2026 breakage (“since the packaging changed to the smaller packs, they break after flossing every tooth.”), and the two accounts that praise them have hidden comment histories, so we could not check them; if you want a cheaper Platypus, Fremouth is the one commenters name, with those caveats. Oral-B Glide Threader Floss, a floss with the threader built in, was one r/DentalHygiene commenter’s favourite (“Glide threader floss is the best. Makes it so easy to floss under bridges and retainers.”), and a self-described hygienist with a bonded retainer used it in 2022. Commenters in the biggest r/braces thread we read say it has been replaced: one reports calling Oral-B in late 2024 and being told “They confirmed that they discontinued the Glide threader floss.”, another ordered from three Amazon sellers and “each one has sent me Oral-B, that I’ve needed to return”, and a flaired hygienist in another thread found it on back order. The listing we read holds 4.3 stars across 13,991 ratings with 13% one-star, from a third-party seller at about $26 for four packs; we did not read its newest reviews and have not linked it. Tonochi 2-in-1 Threader Floss is a new 2026 listing whose reviews pool four different Tonochi flosses, so its 4.5 stars are not this product’s; not linked. Cocofloss’s CocoPlush threaders sit at 3.9 stars, below the line we use for a card. A water flosser comes up in 36 of the 53 threads we read; the trial above found it removed about as much plaque as super floss in braces patients during one cleaning, the AAO lists it under additional tools, and the ADA says it can help people with braces and bridges. Our braces water flosser page compares them.
How to Floss With Braces
- Expect the first two weeks to be slow. A new braces patient who was handed Super Floss asked r/braces, “I thought this superfloss stuff was supposed to make it easier??” after an hour at the sink; a commenter in another thread answers the question most people have: “It took me 20 minutes to floss the first time with braces now it takes me 3-5 minutes with super floss / threaded floss. Do it every night.” Sit down and use a lighted mirror; one practised commenter’s tips: “Tie a knot in your floss in the loop, and use your tongue to help guide the floss threader around your mouth so you can grab it. Thread away from your gums so you don’t poke yourself.” The AAO’s advice is simply at least once a day.
- Threader method. Break off about 18 inches of floss (the ADA’s own flossing steps), pass one end a few inches through the loop, and push the loop’s tip under the archwire from the outside in. Pull the floss through, let the threader fall away, and floss that gap the ordinary way: curve the floss into a C against one tooth, slide it gently below the gumline, rub up and down, then repeat on the neighbouring tooth, as the ADA describes. Pull the floss out from the side rather than up through the wire; commenters say waxed or smooth floss catches less on brackets than unwaxed.
- Flosser method. Slide the thin flat arm under the wire so the floss sits between two teeth, work the floss down to the gum in the same C shape, and lift it out under the wire the way it went in.
- Bleeding gums are a reason to keep going, gently. The AAO says that in most cases you should not stop cleaning an area because it bleeds a little, and to contact your orthodontist or dentist if bleeding “persists, becomes heavier, occurs without brushing or flossing, or is accompanied by significant pain or swelling”.
- Finish with the brush you cannot floss with. An interdental brush around each bracket, which the AAO lists under additional tools, and a water flosser if you own one; our braces toothbrush page and interdental brush page cover both. Braces wax is for the wire that is cutting you, not for flossing.
Flossing Under a Bonded Retainer
A bonded retainer is one wire glued behind the lower (sometimes upper) front teeth after braces come off, and it stays for years. The five-year study above found more calculus on those teeth in the retainer group, so this is the gap where threading pays. The threads about it are the most anxious ones we read: “the gaps between those teeth are so tight that even my dentists have been unable to get floss or anything in there. Is this dangerous?” asked one r/DentalHygiene poster, who added, “I’m low on money with no insurance”; an r/askdentists poster using a threader says “I get basically no leverage” and has plaque building up there. The pattern in the answers is consistent: soft loops fold, so people move to a firmer threader (BridgeAid) or a threader floss (GUM EasyThread, or Super Floss if your box still works). The flaired hygienists add technique: for an upper retainer, “have the pt tilt their chin up as high as possible and get the floss from palatal side”; one says “I will often bend my floss threader to a 90-degree angle”; and as an r/adhdwomen commenter pointed out to a poster using a new threader every time, “you only need to use one of those blue threaders per flossing session”. Two flaired hygienists in the r/DentalHygiene thread recommend a water flosser for people who cannot floss round a retainer (“Yes, get a waterflosser!! Thats what I tell all my patients who have trouble flossing around those retainers!”), and a third answers the poster who hoped that meant flossing was optional: “It’s super important to floss around retainers and all teeth”. Some readers use the smallest interdental brushes or soft picks there instead; our interdental brush page covers sizes. Calculus that has already formed under the wire comes off at a cleaning, not with floss, which is why the orthodontist in one thread paired the water flosser advice with keeping up the dental visits. If nothing will pass between a tooth and the wire, do not force it; ask a hygienist to show you the angle.
Flossing Under a Bridge or an Implant Bridge
A fixed bridge joins two or three crowns, so nothing drops between them; the floss goes under the span and along it. One r/DentalHygiene poster with a new front bridge could not get a threader behind it at all and was “stabbing myself with the threader”; the flaired hygienist who answered asked where and with which threader, “some are easier than others”, and an unflaired one in a second thread offered the approach that works for her: “If you can’t get in from the buccal, try from the lingual.” A later commenter in the bridge thread found that store-brand threaders went where Super Floss would not (“I couldn’t get Orabl B superfloss over my bridge consistently, no matter where I poked. Switched to a threader, bought store brand, and bam.”), and another warned that a bridge you cannot clean under is urgent: “you should DEFINITELY see your dentist ASAP if you can’t floss under your bridge because your abutment teeth will start to decay”. For a full-arch implant bridge, the largest thread we read (r/Dentalimplant, 78 comments) split: the poster had been shown a Waterpik and nothing about floss, some commenters said “Waterflosser is a good alternative to superfloss. You don’t need both.”, one was told so by a prosthodontist second-hand, and others thread Super Floss under the bridge (“My dentist says to just use the waterpik but my last dentist said to use superfloss.”). Our rule from the dental floss page stands: a threader or super floss under an implant bar, and your implant dentist’s instruction over any page, including this one.
Our Methodology
We built this page by appliance and by gap, because readers with braces, a bonded retainer and a bridge arrive with different problems and the same search. Products had to be a tool for getting floss under an obstacle, sold on Amazon US, with a rating that belongs to the product (packs of the same item count, different products sharing a listing do not), at least 100 ratings, and some support outside Amazon: commenters in the threads we read, a professional’s recommendation, or a long record under the same brand. For ten candidates we read the newest 50 written reviews and compared their average with the lifetime figure, judged against the spread across the whole group rather than one product; we did not run that read on Oral-B Glide Threader Floss or CocoPlush. That read removed Plackers OrthoPick (far outside the range, with one fit complaint repeated for fourteen months); GRIN stayed inside the range by the number but was left out for its wire-damage complaints and the absence of any commenter naming it; Super Floss appears without a badge and outside our top picks, with its 2026 complaints on the card; a shared rating pool removed Tonochi; a 3.9 rating kept CocoPlush off; Fremouth is named in the text with its caveats rather than carded. Every Reddit quote was read on the live thread on the day we wrote this; deleted comments were not used, one account whose name reads as a dental chain’s was set aside, and counts are of distinct commenters naming a product, not of verified owners. Where a commenter’s profession is a claim rather than the subreddit’s own flair, we say so. We did not test these products. Prices are the Amazon price on the day we read it and will change.
Community vs. Evidence
| Topic | What Reddit says | What the evidence says |
|---|---|---|
| Flosser or threader for braces | Platypus named by 84 commenters in 27 of 53 threads, for speed and the C-shape; in 7 of the first 20 threads a commenter’s tool failed on tight or crowded teeth and they switched, often to a threader and waxed floss | We found no trial comparing them; the AAO names both as options; one orthodontic practice’s page recommends both |
| Super Floss | The most-named product, 93 commenters in 43 threads; praise for the stiff end and two thicknesses, complaints about fibres on brackets, gum soreness, tight teeth and a soft threader end; one 2026 commenter says it “used to work better years ago” | The one braces trial we found used it and measured no significant difference from a water flosser in one cleaning; both Amazon listings carry 2026 complaints of a changed product |
| Does a water flosser replace floss? | An extra, not a swap, in 5 of the first 20 threads; one dissenter whose dentist found Waterpik-only teeth “almost perfectly clean”; two flaired hygienists recommend one for retainer wearers who cannot floss, a third insists on floss too; all-on-x implant owners split | The 2022 trial found no significant overall difference in one cleaning, the water flosser better behind the molars; the AAO lists it under additional tools, the ADA says it can help with braces and bridges |
| Permanent retainers | 5 of the first 20 threads: threading hurts, gives no leverage, or will not pass at all; firmer threaders, threader floss, the chin-up palatal angle and a water flosser as the extra | Five-year data: more calculus under a fixed retainer, no significant difference in recession; a 2019 review says they “complicate maintaining oral hygiene” |
Frequently Asked Questions
What is the best floss for braces?
The tool matters more than the floss. An orthodontic flosser (Platypus) is the one commenters call quickest; a loop threader with waxed floss is cheapest; threader floss (GUM EasyThread, or Super Floss) combines the two in one strand. Commenters say waxed or smooth floss shreds less on brackets than unwaxed, and the AAO names a floss threader or an orthodontic flosser as the tools to add, along with whatever your care team recommends.
Is Super Floss still good?
The product has a braces trial behind it and is the most-named strand in the threads we read. Buyers on both Amazon listings report a 2026 change: a different threader end, new packaging, and on the 50-strand box shorter strands, and the newest reviews average 3.1 to 3.6 stars against 4.4 to 4.5 lifetime. It is on this page with that caution and without a badge. If your current box works, keep using it; if a new box disappoints, the GUM EasyThread is the same idea from another maker. We will re-read both listings in January.
Does a water flosser replace floss with braces?
The AAO lists it under additional tools and the ADA says it can help people with braces and bridges reach what other tools miss; neither says to drop floss. In the braces trial we found, a Waterpik and Super Floss removed about the same plaque in one cleaning, with the Waterpik better behind the molars, so it is a strong second step. The hygienists in the threads we read still want floss where it can reach; the dissent is one braces wearer whose dentist found Waterpik-only teeth “almost perfectly clean”.
How do you floss with a permanent retainer?
A threader under the wire for each of the gaps the wire crosses, usually the six lower front teeth, then ordinary flossing of that gap. Firmer threaders pass more easily than soft loops; a threader floss does the same job in one strand. Hygienists on r/DentalHygiene add two tricks: approach an upper retainer from the palate with your chin up, and bend the threader to a right angle. Expect a learning curve, and ask your hygienist to show you the angle if it hurts.
Why does floss shred or catch on my braces or bridge?
Brackets, hooks and the edges of a bridge catch unwaxed floss first; commenters say waxed or smooth floss through a threader catches less, and shredding is how two of the threads we read open (“they all “shred” snag or peel apart when i floss”). If you are looking for Oral-B Glide Threader Floss because it used to work, commenters say it has been replaced and that the replacement shreds. If floss catches on a crown or bridge every time at one spot, a self-identified dentist and another commenter on r/Dentistry say that points to excess cement, an open margin or a tight contact, which is a check-up, not a floss problem; our dental floss page has that discussion and the PFAS question on smooth flosses.
How often should you floss with braces?
Once a day, every day, per the AAO; its between-visits page says flossing is “even more important” with an appliance because food left against a bracket is “a recipe for cavities”. Pick the tool that you will use at that frequency, which is the whole argument for the flosser over the threader for teenagers.
