"The best floss. I’ve tried plain, waxed and flavored dental flosses, and Akamai’s infused black floss is hands down the best. It is much less likely to cut into the gum between my teeth, AND it cleans SOOO much better." — C. Bow

The Ultimate Floss

We spent hundreds of hours researching and testing a wide range of tools designed to remove bacteria between teeth and gums. Everything from dozens of floss brands and styles — including silk floss (breaks, just ok at removing plaque and bacteria), Glide (nasty chemical coatings), and others. We also tried oral picks (tons of plastic waste, bulky, expensive) and other tools.

None did the job as we envisioned. We thought…

  • Why not optimize floss so that in addition to removing plaque, it was infused with ingredients beneficial to oral health? Doing so was a real technical challenge as we worked with our dental advisors and engineers at our manufacturing partner.
  • Why not drastically cut waste & make it refillable? Our Refillable Floss System™ does that, reducing waste by more than 70% over traditional flosses. When empty, simply pop open the case and insert a new bobbin.
  • Why not utilize advanced thread technology? Our floss uses an advanced multifilament thread technology made up of 500+ filaments — each strand thinner than a human hair. Our multifilament threads expand to grab more crud from between teeth and gums. It physically traps and removes more bacteria.
  • Why not make it a color that is helpful? We chose black as a color that helps give a visual guide for the amount of stuff you are extracting.

The more we researched the more we realized how crucial flossing is to oral health.

Did you know?

  • Poor oral health and gum disease can be linked to several ailments, such as endocarditis, heart disease, rheumatoid arthritis, diabetes, premature birth, and many other health conditions like pneumonia.
  • An estimated 300-500 species of bacteria live inside our mouths and can be found in plaque. While some are beneficial, most are not. Look under the microscope.
  • According to a Delta Dental national public opinion poll of American adults, 20% of adults never floss, and 32% of adults reported no flossing in the past week.

How to use

  1. Use approximately 14 - 18” of floss.
  2. Gently slide it against the side of each tooth, with a motion to draw debris away from the gum.
  3. Advance to a clean section of floss each time before inserting.


Establish a solid flossing routine. Here’s what works for us.

  • Try to do it at the same time, every day.
  • Miss a day (or several)? Just floss at your next designated time. Don’t beat yourself up.
  • Make a visual reminder. Keep your floss on your bathroom sink, in your purse, or car console.
  • Don’t run out. Just like a core supplement, this good habit can die if you run out. (Consider subscribing to our spool refill as a reminder for yourself —“It's gonna keep coming and I want to do this daily”).
  • While flossing, remember that this simple task can support whole body health and remove bacteria that contributes to bad breath.

Haven’t flossed in a while? Like with our tongue cleaner, use the appearance and the smell (yikes!) of what you remove as inspiration to keep it up. Yep, it’s kinda gross, however, it does provide great inspiration to make flossing a part of your daily oral hygiene routine. So, get on it and get it out of your mouth daily!

Q: Will your floss work for people with tight teeth spacing?

A: While our floss works for most teeth, if your teeth are really tight our floss may not work for you.


Q: Why should I floss daily?

A: According to the Academy of General Dentistry (AGD), flossing is the single most important weapon against plaque. By flossing your teeth daily, you increase the chances of supporting healthy gums and keeping your teeth a lifetime.

Q: How do you use the refill system?

1. When empty, pop open the case & remove the old spool’s plastic ring.
2. Insert a 2-month refill spool.

Q: What if the spool doesn't fit?

A: During manufacturing, slight overrun variances can occur during high-speed spooling of thread. If this happens, extra floss needs to be unwound and cut in order for the replacement spool to fit in the case. Simply unwind a bit, cut off the excess and insert spool. We understand this is not ideal and are working with our manufacturer to fix the issues.

Q: What if the small metal part (floss cutter) comes loose?

A: Just slide it back into position. To avoid losing this piece, be sure to open the container and change over a flat surface (not your sink!).

Flossing questions answered by the American Dental Association

  • When’s the best time to floss?
    The ADA recommends brushing twice a day and cleaning between teeth with floss (or another interdental cleaner) once a day. Some people prefer to floss in the evening before bedtime so that the mouth is clean while sleeping. Others prefer to floss after their midday meal. Still, others chose to floss first thing as a part of their morning ritual. The bottom line is that the best time to floss is the time that fits well with the individual’s schedule.
  • Should I brush or floss first?
    According to ADA, either is acceptable as long as you do a thorough job. Some people like to floss before brushing to better ensure that any material between teeth is swept out of the mouth. Others prefer to first clean their mouth by brushing before working with floss between their teeth. However, those who brush their teeth and skip flossing because they think their mouth feels clean or are short on time or tired and postpone flossing for some later time are likely missing out because flossing may never happen.
  • Can I rinse and reuse floss?
    The ADA does not recommend using a floss strand more than once. Used floss might fray, lose its effectiveness, or may deposit bacteria in the mouth. Discard after use.

70% less waste with our Refillable Floss System™

  • If everyone on our planet flossed 1x a day, the plastic containers disposed of in a single year could fill a football stadium 6 stories high.
  • Our floss container can be refilled many times. Using our refills and the original container has the potential to cut plastic waste by 70% or more.
  • Subscribing to our refill spool of floss not only has an environmental benefit but will keep you reminded to keep up with your beneficial floss routine.

What's not in it

  • No synthetic flavorings — either totally artificial or “naturally derived”.
  • No chemical coatings commonly found in many flosses. E.g Perfluorochemicals (PFCs) (added for the “glide factor”) which are linked to thyroid disease, dementia, cancer, fertility issues, and birth defects. Read more on the study here.

Regarding "100% Natural"

The ingredients, meaning the infusion, are 100% natural (comprising of essential oils, fulvic acid and beeswax) - the floss material itself is a nylon microfiber. We choose to use this material since it is far more effective at grabbing and removing plaque than silk.

I love my black floss especially knowing where I need to work a bit more and floss again until it comes out clean


I only use this floss.


This is the best floss I have ever tried!


Love it!!!!

Amy H.H.
Teeth feel & look clean! And, breath is fresh!

I’m really surprised by this product. I had heard of remineralizing teeth, but didn’t know what to use. I found Akamai and decided to try it. WOW! First thing I noticed was fresher breath. My teeth aren’t as sensitive and they feel cleaner. I’m only one month in - can’t wait to hear what my dentist says in December!

Black Floss

It’s great! So much better than drug store floss. I love it!


Best floss iv ever used


I was concerned the floss was going to be too thick making it difficult to get between my tight teeth. I have had no issues. I love that it doesn’t shred and my teeth feel cleaner compared to other flosses I’ve used. Now I’m just worried I’m going to run out of this awesome floss too soon. Highly recommend.

Infused Blask Floss

Love this stuff. After years of trying several types of floss, this one is the BEST.
I've ordered a few times now. Will continue to do so. Infused Black Floss is
a keeper!

Black floss

Not a fan of this it frays horribly and gets caught between my teeth

Hi Jeanette!
Thank you for your feedback - we know that the Floss does not work as well for people who have tight teeth - it behaves as you described.

I issued a store credit for you for 1 of the Infused Floss Containers ($8.95) - you will receive an email from Rise.ai with your code.

Kindest regards, Sarah
