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: Great Floss! - It's thick, easy to grasp and use, and doesn't cut my lips or gums. The cardamom flavor is unusual, and I think I"ll try a different flavor when I re-order.

### ⭐⭐⭐⭐⭐ Best floss ever!
*by M***L on December 21, 2025*

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!
