Best Dental Floss: Picks For Tight Contacts, Braces, And Everyday Use

The best dental floss depends on how tightly your teeth touch, whether you wear braces, and which method you will stick with every day. This guide compares string floss, expanding floss, orthodontic flossers, and floss picks, with a clear pick for each situation.

TL;DR

• Choose thin, smooth floss for tight contacts and expanding floss for mixed spacing.

• Use orthodontic flossers or Super Floss under braces wires and fixed retainers.

• Switch to interdental brushes where the spaces are wide enough to fit one.

• Floss once a day with a C-shaped wrap, since technique beats any price tag.

What Makes A Good Dental Floss?

A good floss is one that reaches below the contact point, hugs the side of the tooth, and survives the trip without shredding. Which product does that best depends on your mouth more than on the brand.

Several features decide how a floss performs:

• Thickness, which decides whether it passes a tight contact or fills a wider space

• Shred resistance, especially around fillings, crowns, and rough edges

• Flexibility, so it can wrap into a C-shape around the tooth

• Surface, with smooth strands sliding easily and textured ones gripping more plaque

• A stiff end or threader for braces, bridges, and fixed retainers

• Softness for inflamed or sensitive gums

• Disclosed materials and coatings

The evidence supports cleaning between the teeth every day. The ADA notes that floss and interdental brushes used with brushing may reduce plaque and gingivitis more than brushing alone. It also points out that floss suits tight spaces, while interdental brushes suit people with gum disease or wider spaces.

That second point gets overlooked. Many adults with receding gums keep buying floss for spaces where a small brush would clean far better. Our guide to the best interdental brushes covers sizing.

What Are The Different Types Of Dental Floss?

Floss comes in more forms than most shoppers realize, and each one solves a different problem.

Wax does not change how well floss cleans. The ADA states there is no difference in effectiveness between waxed and unwaxed floss, and it is generally how and when floss is used that matters.

What Are The 8 Best Dental Floss Products?

The eight products below were selected on construction, intended use, manufacturer specifications, current US pricing, ADA Seal status where verified, and clinical suitability. They were not lab-tested for this guide. Prices are approximate US retail figures and change often.

#1. Dr. Tung's Smart Floss

Smart Floss is a multifilament polyester floss that starts thin and expands as you work it between the teeth. That behavior makes it unusually versatile. It slips into most contacts, then fluffs out to fill the space and grab plaque on the tooth surface.

It is lightly coated with plant and beeswax, flavored with cardamom and free of PTFE and PFAS. Very tight contacts can still fray it, so patients with crowded lower front teeth may prefer a smoother strand.

• Price: About $5.50 to $6.50 for 30 yards

• Where to buy: Amazon, Target, Whole Foods, and natural grocers

• Material: Polyester multifilament with plant and beeswax

• Type: Waxed expanding floss

• Length: 30 yards (27 meters)

• Best for: Everyday use with mixed spacing

Pros:

• Expands to cover more tooth surface

• Free of PTFE and PFAS

• Soft on gums and fingers

Cons:

• Can fray in very tight contacts

• Paper dispenser weakens when wet

#2. Oral-B Glide Pro-Health Original

Oral-B Glide Pro-Health Original has long been the floss dentists hand out for tight contacts, because the strand is thin, smooth, and very hard to shred. It carries the ADA Seal of Acceptance. 

The formula has changed, though. Oral-B says Glide is no longer made with PTFE and now uses a micro-textured nylon and elastic fiber, so it feels slightly grippier. Some long-time users dislike the new texture. Check the box when you buy, since older stock may still be on shelves.

• Price: About $4.50 to $5.50 for 50 meters

• Where to buy: Amazon, Walmart, Target, CVS, and most grocery stores

• Material: Micro-textured nylon and elastic fiber, per Oral-B

• Type: Shred-resistant monofilament-style floss

• Length: 50 meters (about 55 yards)

• Best for: Tight contacts and rough or crowded teeth

Pros:

• Thin enough for the tightest contacts

• Highly shred-resistant

• ADA Seal of Acceptance

• Low cost per use

Cons:

• New fiber feels different from the original

• Smooth strand grips less plaque in open spaces

#3. Cocofloss

Cocofloss is a woven floss made from about 85% recycled polyester, infused with coconut oil and lightly coated in vegan wax. The weave has hundreds of fine threads that compress to enter a contact and spread out once inside.

Patients often say it feels like scrubbing, which suits normal spacing. It is free of PFAS and parabens. The trade-offs are price and thickness. It costs about three times as much per yard as Glide, and it can catch in very tight contacts.

• Price: About $10 for 33 yards

• Where to buy: Amazon, Target, Walmart, and the brand's site

• Material: Woven recycled polyester with coconut oil and vegan wax

• Type: Waxed woven expanding floss

• Length: 33 yards (30 meters)

• Best for: Normal spacing and people who want a textured feel

Pros:

• Textured weave grips plaque

• PFAS-free, refillable dispenser

• Gentle on gums

Cons:

• Highest cost per use in this list

• Too thick for some tight contacts

#4. Platypus Orthodontic Flossers

Platypus flossers solve the main reason braces patients stop flossing, which is threading floss under the wire for every single contact. A thin, flexible arm slides beneath the archwire, and the floss then pops down between the teeth in one motion. Most patients can floss a full mouth in a couple of minutes.

Each one is meant for a single session, so the cost adds up over a long treatment. They do less for the gumline around each bracket, where a small brush still helps.

• Price: About $8 for 30 flossers

• Where to buy: Amazon, Walmart, and orthodontic supply stores

• Material: Plastic handle with nylon floss

• Type: Orthodontic floss pick

• Quantity: 30 flossers

• Best for: Fixed braces

Pros:

• No threading needed

• One-handed and fast

• Designed around the archwire

Cons:

• Higher cost per day than threaders

• Less useful after braces come off

#5. Oral-B Super Floss

Super Floss combines three tools in one pre-cut strand. A stiffened end threads under a bridge or wire, a spongy section cleans around appliances and wider spaces, and a regular floss section reaches below the gumline.

That makes it the best everyday option for fixed bridges and bonded retainers behind the lower front teeth, where tartar builds quickly. The spongy section can fray on sharp edges, and the strands are too thick for tight contacts.

• Price: About $4.50 to $8 for 50 strands

• Where to buy: Amazon, Walmart, CVS, and most pharmacies

• Material: Nylon

• Type: Specialty floss with threader end

• Quantity: 50 pre-cut strands

• Best for: Bridges, fixed retainers, braces, and implants

Pros:

• Built-in threader end

• Spongy section cleans around appliances

• Pre-cut for consistent use

Cons:

• Too thick for tight contacts

• Spongy section can fray

#6. GUM Eez-Thru Floss Threaders

Eez-Thru threaders are flexible nylon loops that pull your usual floss under braces wires, bridges, and fixed retainers. They are the cheapest way to clean under appliances, and they let you keep using a floss you already like.

Threading takes practice, and doing it for every contact with braces is slow. That is why many orthodontic patients use threaders for a retainer or bridge and dedicated flossers for braces.

• Price: About $3 to $5.50 for 25 threaders

• Where to buy: Amazon, Walmart, and most pharmacies

• Material: Nylon monofilament loop

• Type: Floss threader

• Quantity: 25 threaders with storage case

• Best for: Fixed retainers and bridges on a budget

Pros:

• Works with any floss

• Lowest cost for appliance cleaning

• Includes a storage case

Cons:

• Slow to use for a full set of braces

• Takes practice to master

#7. Plackers Twin-Line Floss Picks

Twin-Line picks hold two parallel strands of Plackers' Tuffloss fiber, so each pass covers a little more surface. The fold-out pick on the handle helps clear food from the gumline. They are inexpensive, widely available, and easy for people who struggle to wind string floss around their fingers.

Two strands do make tight contacts harder to pass, and some recent buyers report more breakage than in the past. Picks also cannot wrap into a full C-shape, so they clean the side of the tooth less thoroughly than string floss.

• Price: About $4.50 for 150 picks, or $7 to $9 for 300

• Where to buy: Walmart, Target, Amazon, and most grocery stores

• Material: Plastic handle with Tuffloss synthetic floss (fiber not disclosed)

• Type: Double-line floss pick

• Quantity: 150 or 300 picks

• Best for: Everyday convenience and normal spacing

Pros:

• Two strands per pass

• Very low cost per pick

• Built-in fold-out pick

Cons:

• Harder to pass through tight contacts

• Some reports of breaking strands

#8. DenTek Triple Clean Advanced Clean Floss Picks

DenTek Triple Clean picks use a single, thin floss made of more than 200 fine strands, which helps them pass tight contacts that defeat double-line picks. The floss is fluoride-infused and mint-flavored, and the handle adds a textured pick and a small tongue scraper.

Their low price makes them easy to keep in a bag or car. As with any pick, wrapping around the tooth is limited, so they work best as a supplement to string floss or for people who would otherwise not floss at all.

• Price: About $4 to $4.50 for 150 picks

• Where to buy: Walmart, Target, Amazon, and pharmacies

• Material: Plastic handle with multistrand floss (fiber not disclosed)

• Type: Single-line floss pick

• Quantity: 150 picks

• Best for: Budget floss picks and tight contacts

Pros:

• Thin enough for most tight contacts

• Very low cost per pick

• Textured pick and tongue scraper

Cons:

• Limited wrap around the tooth

• Floss material not disclosed

How Do The Best Dental Floss Products Compare?

Pack sizes vary widely, so the last column shows an approximate cost per flossing session. String floss figures assume 18 inches per session, the length the ADA suggests.

Even the most expensive string floss here costs about 15 cents a day. The cheapest floss you use every day beats a premium spool that sits in a drawer.

What Is The Best Floss For Tight Teeth?

Tight contacts are where floss fails most often. It catches, frays, or snaps through and slaps the gum underneath.

The best floss for tight teeth is thin, smooth, and shred-resistant. Oral-B Glide Pro-Health Original is the strongest pick from this list, and DenTek Triple Clean is the best pick-style option. Woven and double-line products tend to struggle.

Technique matters as much as the strand:

• Ease the floss through the contact with a gentle back-and-forth sawing motion

• Never snap it down onto the gum

• Wrap it into a C-shape and slide it just below the gumline on each tooth

• Pull it out sideways if it catches, instead of yanking upward

A floss that shreds on the same contact every time is telling you something. The usual causes are a rough filling edge, a chipped tooth, tartar, or early decay between the teeth. A dentist can smooth or repair the spot in a few minutes.

Food that packs into one space after every meal points to a different problem, covered in our guide to food getting stuck between teeth.

What Is The Best Floss For Braces?

Braces turn a two-minute habit into a ten-minute chore, because the archwire blocks the floss from reaching each contact. The right tool brings it back to a few minutes.

• Orthodontic flossers slide under the wire in one motion and are the fastest option

• Super Floss has a stiff end that threads under the wire and a spongy section for brackets

• Floss threaders pull regular floss under the wire for the lowest cost

• Regular floss alone only works if paired with a threader

For most braces patients, Platypus Orthodontic Flossers are the best floss for braces because they are quick enough to use every night. Super Floss is the better choice for fixed retainers and bridges after treatment.

Many patients also like a water flosser for flushing around brackets, which our oral irrigator guide covers, alongside a suitable toothbrush for braces.

What Are The Best Floss Picks?

Floss picks appeal to people who find string floss fiddly, have arthritis, or need one free hand. A pick used every day is better than string floss used once a week.

When choosing the best floss picks, a few features matter:

• Single-line picks pass tight contacts more easily than double-line picks

• A longer, angled handle helps reach the back molars

• Shred-resistant floss avoids snapping mid-mouth

• Orthodontic picks are a separate category built for braces

DenTek Triple Clean is the best everyday pick for tight teeth, and Plackers Twin-Line suits normal spacing. Picks are single-use plastic, so they create more waste than a spool. The ADA also advises against reusing interdental cleaners, since a used strand can fray and redeposit bacteria.

Waxed Vs. Unwaxed Floss: Which Is Better?

Neither type removes more plaque. The difference is in how they feel and how easily they pass between teeth.

Waxed floss slides more easily and resists fraying, which helps with tight contacts. Some people prefer unwaxed floss for the squeak it makes against clean enamel. The ADA reports no difference in effectiveness and notes rare cases of sensitivity to waxed or coated floss.

Pick whichever you find more comfortable, then focus on using it daily.

Floss Picks Vs. String Floss: Which Cleans Better?

String floss cleans better when used well, and floss picks clean better when they are the only thing someone will use.

A practical compromise works for many patients. Keep string floss for the evening and picks in a bag or car for the times you would otherwise skip it.

Is PFAS-Free Dental Floss Better?

PFAS-free floss is not proven to clean better. The appeal is about chemical exposure, and the research there is limited.

PTFE, the slippery material best known as Teflon, belongs to the PFAS family. A Silent Spring Institute study of 178 women found that those who used Oral-B Glide had higher blood levels of one PFAS compound, PFHxS.

The researchers found an association and did not prove the floss was the source. All three Glide products they tested contained fluorine, consistent with PTFE.

The market has moved since then. Oral-B now states that Glide no longer contains PTFE or any PFAS. No independent testing of the new fiber has been published yet, and older stock may still be in stores.

Nylon, polyester, and silk flosses do not rely on PTFE, though coatings vary, so check the label. For shoppers who want to avoid PFAS, Dr. Tung's and Cocofloss both state they are free of it.

How Do You Choose The Right Dental Floss?

Start with the spaces between your teeth and any dental work, then pick the product you will use every day.

Bleeding for the first week or two of daily flossing is common while inflamed gums settle. Bleeding that lasts beyond two weeks can be a sign of gingivitis and deserves a checkup. A persistent bad smell on used floss can also point to a problem, explained in our guide to why dental floss smells bad.

A dental hygienist is the best person to match a tool to your mouth, especially with implants, a dental bridge, or gum disease. Many practices now record those recommendations in dental treatment plan software, so the advice is waiting for you at the next visit.

For the order of your routine, see whether to floss before or after brushing, and our best xylitol gum guide covers an easy addition between meals.

Bottom Line

The best dental floss is the one that fits your spaces and that you will use every day. Dr. Tung's Smart Floss is the best all-round choice, Oral-B Glide Pro-Health Original suits tight teeth, and Platypus flossers make braces manageable.

Floss picks are a fair substitute when string floss would otherwise be skipped. Daily, careful cleaning between the teeth matters far more than any premium price.
