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).

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!
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!

Great floss, our go-to floss! Better than anything sold in stores.
Our household go-to floss. It’s very soft on the teeth so even people with “tight” teeth can use it and it doesn’t hurt. I like that it expands.

Love it, wish it wasn't so expensive
This floss is wonderful stuff. I don't like the big brands floss - they are very plastic, and don't seem to remove plaque. Hate the Glide stuff. I really really don't want to rub PFAS, etc. into my gums. Dr Tung's really is comfortable and I think it's removing plaque much better than any I've used before. I wish it wasn't so expensive (had to take off a star) but I like it so much I guess I'm going to have to buy it again... unless I can find another brand that works as well.

Best floss I’ve ever used
I was reluctant to buy this due to price, but my dentist recommended it. I’m glad I purchased it. The floss is thick and very strong. I think it’s the strongest floss I’ve ever used. I had been using a better known and easily available brand. Those floss strands were thin and would often break. Going forward, I will be using DrTung’s floss.

nice and natural
was using a similar product but they had none without "flavors" and those flavors had sweeteners i didnt want. tried dr tungs and like the floss very much and it is not coated so cleans better. getting ready to order more

Better than cocofloss?
Once I discovered expandable floss I could not go back to the regular stuff. It makes such a big difference. Well I had run out of my usual cocofloss so I decided to give Smartfloss a try since it is significantly cheaper. And Wow! I love it. I think even more so than cocofloss because it leaves a nice minty clean after taste. I am glad I found a new staple in my routine. The eco friendly packaging is a huge plus too.

being using oral-B, this is clear setup from it. slides in as easy without stredding. soft cloth texture with ample material so you won't slip and cut into gums like the B boys. no weird flavor, this is good my friends except its twice the B price...

香りもありとてもいいフロスと勧められ在庫があったので購入してみましたが高額の割に特別の良さは、あまり感じませんでした。香りがカビ臭く感じたのが残念でした。もう一種類を使用してから次をどうするか決めようと思っています。

Tengo las encías retraídas y sensibles y me daba miedo pasar la seda/hilo dental todos los días porque me hacía algo de daño en alguna encía. Éste es maravilloso, el mejor que probado nunca, lo uso a diario y noto que limpia y arrastra mucho más que el resto y de una forma suave, como si fuera una esponjita entre los dientes, pero cabe perfectamente hasta en los dientes apiñados sin romperse ni hacer daño. Ademas el aroma muy suave a cardamomo es muy original y me encanta

When I found out the floss I had been using for years was loaded with PFAS I started to look for alternatives. I came across this product from a dental blog. It read like a promotional post and looked like an affiliate trying to make some money. But it was so difficult to find a floss labelled PFAS-free that I decided to give this a try and I'm so glad that I did. The floss is strong, expands slightly and doesn't shred easily. I really like the clean feeling after using this. In fact, I was so happy with this floss that I started to use other Dr. Tung products. I've noticed some people have an issue with the new packaging. The plastic dispenser was replaced with a paper/cardboard box and a metal cutter. I don't seem to have an issue with it. It's delicate but I keep it dry and go easy when cutting. What I did find ridiculous was that my two pack of paper floss boxes came wrapped in plastic. As with any specialty product, this is very pricey. Now that I know I like this product I am considering purchasing in a larger quantity to reduce the cost.
