## Description

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.

Review: 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.
Review: Many of us in the dental profession are mourning the loss of Gentle Gum Care woven floss (formerly made by Reach, then Listerine). It’s been the profession’s favorite (my opinion) for years. No one knows what happened to it- you just can’t find it anywhere. So what’s the best alternative? I decided to try out a few candidates. Cocofloss (26 cents/yd)- good sturdy floss, slightly coarse texture, medium thickness, subtle coconut flavor. Dr. Tung’s Smart Floss (14.4 cents/yd)- thickest of the bunch, very soft texture, slight cardamom flavor. Xlent Expandable Floss with Charcoal (~10 cents/meter)- medium thickness, waxy texture, nice mint flavor. Hayden Expanding Floss (~10.5 cents/yard)- only slightly thicker than normal floss, medium texture, subtle mint flavor. First a word about expandable flosses- they only expand when you are not pulling on them. But flossing involves pushing and pulling and scraping up and down. You can’t floss your teeth effectively without putting pressure on the floss. So when you’re flossing, they are not expanded. All four of these flosses splay a bit when flossing, to look more like ribbon. The thicker the floss, the more it splays. So which do I like the best? I like Dr. Tung’s. I love the thickness and the soft, fluffy texture. And I happen to like cardamom, though I will admit it’s not as refreshing as mint. It is a bit more expensive than the cheaper flosses in the group, but not on the level of Cocofloss. I think it’s worth the extra pennies. Cocofloss is good if you want a coarser texture to make it feel like you’re really scraping your teeth, and if you don’t mind paying a hefty premium. Xlent floss was a bit too waxy for my taste, and the black color is a bit odd (though I can’t see it when it’s in my mouth). But I liked its flavor the best and it feels like it does a good job. So if you want the cheapest, but effective floss, it’s the best value. Hayden floss is better than regular floss, but it comes in a distance fourth for me. Of course, you will likely have a different order than I do. But hopefully, this will give you some idea what they’re like. Final note- none of these flosses feel the same as our beloved Gentle Gum Care woven floss. And all of them are more expensive. But to their credit, none of them come unraveled like our favorite woven floss tended to do. And all of them will do a fine job removing plaque. Once I get over the mourning period, I will probably like Dr. Tung’s just as much. RIP
