## Description

desertcart.com : DrTung's Smart Floss - Natural, PTFE & PFAS Free Floss, Gentle on Gums, Expands & Stretches, BPA Free Floss - Natural Dental Floss Cardamom Flavor (Pack of 2) : Health & Household

Review: My Favorite! - Highly recommend this floss. I am one of those people who was highly disappointed when the Listerine woven floss was discontinued. I have been searching for a long time to find a comparable product. I tried the CoCo floss and still disappointed. Also, I do not like plastic and/or wax floss. DrTung's Smart floss works very well any new favorite! I love that is expands and is not waxed. It cleans extremely well. After the first time I used it, I could not believe how clean my teeth felt. I was somewhat hesitate to try this one because of the comments about the taste. However, I love it. It's not as good as the minty fresh taste from the old Listerine but it's very refreshing like a clean essential oil. It did not disappoint. I am thrilled of how well it works, the fact it is natural without chemicals like other flosses, and that it is on a paper container (kind of like a heavy card stock).
Review: Best floss ever! - I searched a while for a high quality floss that wouldn't break and doesn't have PFAS ingredients. When I found this I decided to stop my search. I've used for about 6 months and still haven't broken a piece while flossing. I couldn't even break it when I tried pulling it between my hands. The fabric swells in saliva just enough to provide excellent cleaning. Wonderful product!

## Questions & Answers

**Q: How thick is this floss? I have really "tight" teeth so I need to use ultra-thin floss or it gets stuck.**
A: I wouldn't recommend. I have tight contacts and there were some spots where the floss shredded and I had bits of fiber stuck between my teeth.

**Q: Has anyone compared this with Coco floss?**
A: I LOVE Coco floss. I decided to give Dr Tungs a try. 

The packaging of Dr Tungs is cool, but not as sturdy as Coco floss. The plus is it is made from eco friendly sources. 

The floss itself is very comparable. It has enough wax for it to glide, but not too much where all you feel is wax. 

I like that it expands - similar to Coco floss. 

The Caradamon flavor is refreshing. Much different than the Coco floss. It is not overpowering, which is nice. 

I will purchase both brands again in the future.

**Q: What type of material is the floss made of?**
A: Polyester. Cotton is no longer used in floss as it frays and is harsh. Floss that claims to use bamboo fibers are also harsh and bamboo fibers and textiles are really considered rayon. Silk goes through chemical processes and needs to be threaded or else breaks frequently. Nylon is similar to polyester. Both are from the fossil oil polluters and doesn't biodegrades till 30 years or more although polyester can be recycled. Waterpiks have a limited reach.

**Q: Does the floss itself contain plastic?**
A: If polyester is listed then yes, the floss is plastic.

### ⭐⭐⭐⭐⭐ Soft, comfortable, and thicker
*by B***1 on December 12, 2025*

My dental hygienist recommended these, saying they were thicker. While I've always thought that there wasn't much difference among flosses, that thought changed with the product. I've used string flosses regularly, typically whatever's on sale, though recently I apparently picked on e that looks and feels like fishing line, yuck for me. By contrast, Dr. Tung's is wide and soft. In my last "lesson" from my dental hygienist, she suggested that when the floss picks up something, make a second pass. This is a better product that's worth using on your teeth!
