"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), popular commercial brands (nasty chemical coatings), and others.

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 can help physically trap and remove 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 can be linked to several ailments and imbalances throughout the body.

  • 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 help remove bacteria that contribute 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!

Will your floss work for people with tight teeth spacing?

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

Why should I floss daily?

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 keeping your teeth for a lifetime.

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.

What if the spool doesn't fit?

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.

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

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 health issues. Read more on the study


Ingredients from Nature

The ingredients in our infusion come straight from nature: essential oils, fulvic acid, and beeswax. While we’d love to use silk as the floss, it does not perform nearly as well as expandable nylon microfiber in grabbing and removing plaque.

Highly recommended this floss. Tastes great!


LOVE this floss. Gets all the gunk, very satisfied with the thick thread. So effective, it’s dramatically changed how dedicated I am to flossing. Lifelong customer!

Mary W.
Black Floss

I think black floss is great. Like nothing I've seen in stores. It may be harder to use between extremely tight teeth but works for most all of mine.

Barb D.
Don't want to be without this floss!

I floss twice a day and have done so for years and years. I discovered this Infused Black Floss and fell in love with how thoroughly it cleans. I tried other black floss products and was very disappointed with how easily they shread. This one is far superior and i highly recommend it.


I did not receive the Infused blackberry floss refill

Hi Lisa,
Thank you for letting us know! This typically does not happen. I just refunded you for the amount -- watch for a confirmation email.

Please email us if you ever have any questions in the future!


Thick floss

I love this thick floss that gets all kinds of gunk from between my teeth. I like the smell and knowing that it's safer to use than conventional floss.

Pat G.

Though I like the floss it is difficult to use on my teeth. It’s not waxed and then it shreds.

Hi Pat,
Thank you for leaving a review — we appreciate the feedback!

The floss has the following ingredients and should be waxed:

- Fulvic Acid
- Clove Essential Oil
- Tea Tree Essential Oil
- Ceylon Cinnamon Essential Oil
- Beeswax

I submitted a replacement order for you to try a new one!
