the floss that’s got it all


Plaque stinks! Woven with hundreds of grime-grabbing fibers, Cocofloss erases that sour, stinky plaque to leave your smile fresher than ever.


Plaque's a yellow biofilm that covers our teeth. Cocofloss scrubs all the yellow gunk away to leave your teeth smooth, sparkling, and bright.


Reduce gum inflammation with Cocofloss! Coconut oil, a natural antimicrobial, soothes your gums while Cocofloss fibers scrub all that irritating plaque away.

Treat your teeth to cocofloss

word of mouth


It is full-on over-and-above SUPERIOR to any other floss I’ve tried. I recommend it to everyone — it just… does the job better and less irritatingly...

Jean, Beauty Editor, Goop

If you’re going to fish around your gums for debris, you may as well add some nourishing coconut oil to the floss: Cocofloss glides easier, and it comforts the gums while cleaning house.

The Editors, GQ Magazine

The secret is in the floss itself, a soft filament that’s lightly waxed, durable enough not to shred or tear even with the most aggressive flossing...

Kathleen Hou, New York Magazine

the cocofloss difference

Regularly flossing is one of the best ways to keep gums healthy. Cocofloss cleans what regular floss misses.

regular floss

Regular floss simply moves plaque around (it's so slippery!), enabling plaque to build up. Eek!


Cocofloss is the loofah for your smile! Hundreds of filaments scrub away plaque, leaving your gums purified.

Our Story

dentist buzz

Truly an innovative floss with just the right thickness and texture that slides and cleans proficiently. It gives patients a feeling of satisfaction that they are really making a difference..Patients are addicted which means their dental health has improved.

Dr. Cynthia Bratessani

It’s almost like flossing with unicorn hair. They’ve taken flossing to a whole new level.

Dr. Brian Novy

I instantly fell in love with Cocofloss! The stylish appearance is just the icing on the cake. I have never had a floss clean as effectively as Cocofloss. I notoriously build up plaque and calculus on my lower anterior teeth. But with gentle yet thorough flossing, I am able to maintain it between my hygiene appointments!

Dr. Ashley Harrison

I am just like many of my patients, I hate to floss. Being a Periodontist, I am very picky what I personally use and what I recommend for my patients. I love this floss!!! It is easy to use, cleans great, tastes great and does not traumatize my gums.

Dr. Stephen John
