Best dental floss!
⭐️⭐️⭐️⭐️⭐️ Best dental floss I’ve ever used Dr. Tung’s dental floss is hands-down the best floss I’ve tried. It’s thick, strong, and doesn’t shred or snap like most commercial flosses. It actually grips plaque and food debris instead of sliding over it, so my teeth feel noticeably cleaner after flossing. I also appreciate that it’s coated with natural wax and essential oils—no harsh chemicals or artificial flavors. It’s gentle on gums yet very effective, which makes daily flossing easier and more comfortable. My dentist even noticed an improvement in my gum health. Once you try Dr. Tung’s, it’s hard to go back to regular floss. Highly recommend for anyone serious about oral health.

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).

Best Floss I've Ever Used
Excellent floss. It is soft enough so that it does not irritate your gums although it is very effective at disrupting biofilm and plaque from the interproximal areas (between your teeth). And it doesn't dig into your finger tips and cut your skin as you direct the floss around your mouth. This is a consideration as some nylon thin floss can actually cut into the skin of your finger tips. Overall, highly recommend this brand. Both the mint and cardamom are good flavors. This is completely free of chemicals, according to the manufacturer. The brand is sold in most health food stores and has an excellent reputation. One caveat: if you have very tight embrasures you may not be able to use this floss effectively. If that is the case, try POH floss.

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.

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.

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.

great at its job... the packaging though has been decontented
GREAT floss... would easily get 5 stars, except when we first purchased it came in a circular plastic disc that closed firmly and kept the floss as well as cutting the floss... ever since the paper packaging that has taken over is... disappointing. does not last through the spool. i an skeptical refill discs could not have been created that could be dropped into an existing plastic holder, or that Dr. Tung is saving anything significant over the plastic holders.... so we will keep buying, and keep being disappointed by the new NOT improved holder

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.
