Since “enough of the population flosses to begin with,” Dr. Lau says that most dentists will tell you any floss is better than no floss. But she says the best ones “remove the most plaque and debris from your teeth [before it hardens].” This usually means choosing a floss that’s a bit thicker but doesn’t shred, has some kind of scrubby texture to it, and is coated with a light wax that helps to break up those bacterial colonies, adds Dr. Lau. We researched dozens of flosses and reviewed them based on their material, flavor, type, and price.
Here are the best types of dental floss on the market today.
We’ll admit that Cocofloss is a bit pricier than some other options on our list, but you can shop creatively: according to Cocofloss, one of their spools will last a regular flosser about two months, and the Cocofloss website offers a subscribe-and-save option for fans who want to build their own box of flavors and watch them show up in their mailbox on a predetermined schedule.

He recommends a floss with fluoride or a calcium phosphate, and this expandable floss by RiseWell is one of the only ones to fit the bill: with hydroxyapatite, a calcium phosphate mineral, built into the fibers, RiseWell’s floss is an effective cleaner, fitting smoothly in between your teeth and then expanding to scrub away gunk (and protect your enamel in the process).

An out-of-the-box flavor isn’t the only cool thing about this floss; it’s made with soft, silky fibers and coated with beeswax, allowing it to slip easily between your teeth and then expand as it gets to work on all the plaque lurking in there. It’s only slightly more expensive per pack than other popular drugstore brands, so it’s worth a try if you’re tired of harsh flavors in your dental products.

If a dental pick is the best option for you, we recommend the DenTek Triple Clean Advanced picks, which not only do all the usual flossing work but also feature a micro-textured pointed end for detailed cleaning and a tongue scraper for the freshest possible breath around. The floss itself is made of 200-plus fibers designed not to shred or break, and it is thin enough to fit between tight teeth.

That doesn’t mean flossing with braces is easy, though, so we like the Oral-B Super Floss Pre-Cut Strands for simplifying the whole process. Grab a string and use it like a regular piece of dental floss, in between your teeth, around appliances, and under the gum line. The strands are smooth and spongy, helping to gently but effectively remove debris from your teeth, plus they even have a stiffened end for getting into those tight, awkward corners and easily threading through and around wires, bands, and brackets.

If you have braces, we suggest trying the Oral-B Super Floss Pre-Cut Strands. They dispense easily, fit in and around oral appliances and under the gum line, and come fitted with one stiff end for those stubborn spots that need a little extra attention.
With those notes in mind, we scoured the internet for crowd-favorite dental flosses, considering more than two dozen products. We looked for thick, easy-to-use flosses, flosses designed to expand and optimize their scrubbing power, and flosses made with natural or cavity-fighting ingredients. We also included a few traditional floss alternatives, like picks and strands, for people with braces or dental appliances.
What to Look for in a Floss
Texture
Should you opt for a smooth, thin floss that glides easily between your teeth or one that’s a little rougher, made of woven fibers? Most dentists don’t care as long as you’re using some kind of floss, but if you’re really going for the flossing gold here, there is a difference between the smooth and rough kinds of floss.
“The floss that is probably the most widely used is made of teflon-coated shred-resistant polymer fibers, [and] when you have tight contacts between your teeth, this is probably the most comfortable floss to use,” says Dr. Lau.
But comfort doesn’t necessarily equal effective, Dr. Lau adds: “I personally think that floss is too smooth to truly scrub your teeth; you wouldn’t clean your pots and pans with a smooth, satiny cloth, you [would] use the scrubby side of your sponge.”
If your teeth can handle it, choose a textured, thicker floss with a wax coating, per Dr. Lau’s recommendations: smooth floss will leave a lot of plaque behind, he says, even in avid flossers, but textured floss grabs onto enough plaque to really clean your teeth.
Ease of Use
You’ll have to consider your own oral circumstances when choosing a floss—like if you have braces, or wide gaps between your teeth—as well as your manual dexterity.
“I recommend patients use floss that is most suited to their situation,” says Daniel Reich, DMD, director of Periodontics at Touro College of Dental Medicine. “If a patient has crowding or tight contacts between their teeth, they should use a thinner floss; if [they have] larger spaces, then dental tape may be a better choice.”
People with braces and people who struggle to manipulate string floss may find it easier to use a pick or even a water flosser to be sure they’re getting easily into all the nooks and crannies between their teeth.
Chemical-Free
Some extra-smooth, shred-resistant floss is made with a type of chemical called polyfluoroalkyls, or PFAs; the same kinds often used in non-stick Teflon coatings, which certainly make the floss glide seamlessly through your teeth. But are they safe?
Dr. Lau cites a 2019 study in the Journal of Exposure Science & Environmental Epidemiology that raised concerns about the presence of PFAs in some types of dental floss, since these substances have been linked to some cancers. At the same time, the American Dental Association (ADA) questioned the results of that study, pushing back on the idea that PFAs in dental floss could be harmful.
Whichever side you take in the PFAs debate, know that you have a lot of choices when it comes to picking a floss—and it’s easy to play it safe.
“There are so many options for floss out there, and most do not contain any PFAs,” says Dr. Lau. “Take a look at what goes into [these] products, but I think if you stick to a waxed, textured floss, you will probably avoid these controversial chemicals and [still] get the true desired effect of scrubbing your teeth.”
