There's no other floss quite like Smart Floss!. It is clinically proven to remove up to 55% MORE plaque than regular flosses. It stretches and expands into interdental spaces to clean better. This high-performance floss is suitable for everyone - people with tight spaces, wider spaces...even braces.

This revolutionary floss is also  gentler on gums because it is cushion-soft and can stretch. Unlike those other flosses with no spring that can often hurt gums...and fingers!

Smart Floss dental floss is clinically proven to be more effective than regular floss. It has been shown to remove up to 55% more plaque than some of the most popular flosses, i.e. regular waxed and unwaxed flosses and PTFE monofilament floss (compare to Glide).

Even electric or manual flossers which claim to be as effective as regular floss  are no match for Smart Floss. Smart Floss can clean around the teeth and reach deeper into the interdental spaces, leaving teeth cleaner and you smiling longer!

Now there's no excuse to use a less effective floss.

  • Natural cardamom flavor for a vibrant fresh feeling!
  • Lightly waxed with a natural blend of vegetable and bees wax (no petrochemical wax)
  • Gluten-free. PTFE-free. BPA-free
  • Made of simple polyester fibers
  • Dispenser made with EcoPure, will degrade faster in a landfill than regular plastic (which can take up to 100 years)

(Assorted colors - specific colors cannot be selected)

The only floss I’ll ever use

Review bySue on 02/8/2020

I’ll never go back to drugstore floss again. Dr Tungs is more effective and more comfortable to use than any I’ve ever tried. I just ordered 6 refills so I can reuse my dispenser again and again.

Great Floss---Wish I could get Refill to save on plastic usage!

Review byJordan Maclay on 01/2/2020

This is the best floss, worlds of difference from standard flosses. Really cleans the teeth. When a roll is gone, I hate throwing the plastic container away, even though it is supposed to compost faster than ordinary plastic. It just snaps open and I could insert an new roll of floss! If I had one!! I wish Dr. T would offer this refill option.

DrTung’s answer: Jordan, we DO have refills for your Smart Floss container. Please go to SHOP>ACCESSORIES. Thank you.

Best floss ever!

Review byCorrie on 12/19/2018

I found this floss at my local health food store....and just wanted to share how much I love it! It scrubs and clings only plaque like no other floss. I am so happy I found it.

Hands Down Best Floss EVER

Review byCarrie Biggam on 08/1/2018

When I was 18 years old, my great uncle said to me, "You've got to floss your teeth every day because food doesn't taste the same if you don't have your original teeth." This stuck with me, and I floss religiously. I had been using Reach Dentotape for years, and found that superior to many other brands, but it did hurt my fingers and gums sometimes, as my teeth fit tightly together. Also, my dental hygienist would always find a few "trouble" spots with tarter build up that I couldn't reach. This Smart Floss has changed everything. This stuff is amazing. The first time I tried it my mouth felt like I had never flossed I was reaching new places between my teeth that were sorely overdue for a proper cleaning! After a few days of using it, my mouth felt really different, cleaner, and my gums even felt healthier. Buy this - you'll find yourself recommending it to anyone who will listen!


Review byTrisha on 04/23/2018

I can't believe I'm writing a review for Dental Floss but I am so impressed and yes even excited about this dental floss. My Dentist recommended it to me and it works so much better than Glide. Just as a test I flossed first with Glide and then went back through with this stuff and I was so surprised there was so much crude on the floss from my teeth, it was hard to believe all these years I've been leaving all that stuff behind. No wonder I had cavities.

Love this Floss

Review byBel on 07/6/2017

This is the best floss i have used. Not too thin, doesn't cut gums, thick enough to remove all the bits and pieces as well as plaque. Also, the cardamom flavour is the best!! If that wasn't enough, you can buy refills for the dispenser to save on plastic. Woo!

Best Floss I've ever used

Review byTeresa on 11/17/2016

Several years ago one of the big dental companies made a floss that was very similar to Dr Tung's Smart Floss. It was soft and it expanded the same. I loved it! But they stopped making it.
I was in the local health food shop recently and found Smart Floss and thought I'd give it a go. It's all the things I'd missed about the floss I was using years ago! But even better because it's packaging is more environmentally friendly. Winning on all levels! Please don't ever stop making this!

Life changing

Review byPiotr on 05/21/2016

I know it seems silly to be excited about floss, but holy cow is this stuff amazing! I've used different kinds of floss and thought some were ok and that they mostly are the same thing. I decided to go online and see if there was something different and stumbled up this. Last night was my first time using this and it changed my life. I've never enjoyed flossing but this was an experience! I can finally look forward to flossing and I can't wait for tonight. I don't know what material this is made of but it's like a shiatsu massage for the mouth.

Smart Floss has me flossing DAILY!

Review byElise on 03/3/2016

After years of dental "suffering", I picked up a roll of smart floss on a whim at Whole Foods. I could never manage to keep up a good flossing habit before, but I now remember to floss every single day.
It's a combination of the amazing flavor and performance. No pain and no shredding/sticking.
I'll recommend smart floss to anyone who will listen. The cardamom flavor is really fantastic to me but may be an acquired taste to some.

Definitely the best floss I have ever tried

Review byCasey B. on 02/3/2016

I had been using Tom's of Maine natural floss for years when I switched over to Dr. Tung's due to the former brand being out of stock at my local grocery store. I prefer all aspects of Dr. Tung's floss to any other floss I've ever tried: the clever dispenser, the strength and texture of the floss, and – above all – the flavor. To have a floss with a cardamom flavor is unique, to say the least, and I love how refreshing it is. I'd never enjoyed flossing before, but that has honestly changed – literally from the first day I began using Dr. Tung's. I actually look forward to flossing in the morning now. Thank you for making such a great product!

smartest floss

Review byVivienne on 02/22/2015

the best floss yet! so much plaque removed compared to tape and skinny floss.

Best floss ever!!

Review byChana Feinstein on 02/6/2015

You can't be out of stock -- Nooooooo! (make more please:))

Awesome floss!

Review byNisha on 11/4/2014

I finally enjoy flossing! Lovely to wake up in the morning without a bad taste in my mouth.

Superior Floss

Review byPlynn on 07/1/2014

Dr. Tung's dental floss is far superior to any floss I have used. It does not shred! I can floss in comfort and ease! I love it, but.....

Could you please make the floss without the Cardamom flavor, just plain?

Thank you!

Review byPaul J Keck DDS, MS, Grand Rapids, MI on 06/25/2013

Your floss is significantly better than the traditional floss distributed from dental offices and stores. I ran my own tests. I flossed with traditional floss, followed by Dr Tungs floss, and was astonished at how much additional plaque your floss picked up. It is truly a superior product, and I also like the packaging

Review byAnnie on 08/21/2012

This floss rocks! Makes me want to floss- before using this floss I hated flossing. Won't go back to the old dental floss. No comparison. Make your teeth happy today!

Review byJade on 02/23/2012

I am chemically sensitive. My gums bleed and ache normally after flossing. I switched to smart floss 3 days ago and my mouth has never felt better! I'm really impressed with how well it works too! Can't wait to show my dentist :)

Review byHeather J Nobbe on 02/17/2012

I love this floss. This floss is the only reason I floss my teeth more, NOW, than I ever have in my life. I'm on the site finding out how to recycle this container, and I had to stop and post this.

Review byDawnn Thor on 07/8/2011

Definitely the most awesome floss I've every used! Seriously. Definitely gentler, softer and smarter! Worth 5 stars~!
