"I have a lot of dental issues. I build up tartar / plaque extremely quickly. I have tight teeth, including two spots with sharp edges that break floss even at the dentist's office. I have an implant that traps food under it. I have receding gums. I have sensitive teeth, including a front crown that's historically been painful to floss around. I've also had problems recently with stain accumulating between my teeth. So, for obvious reasons, I was hesitant to switch away from the floss I'd used for years, Glide. However, for environmental reasons, I decided to give this zero-waste, plastic-free floss a try. I'm very glad I did.

This floss is better in every way. It's about the same thickness as Glide, but it's a little less waxy (though it's definitely not unwaxed). As a result, it does a great job of taking off both the tartar and the stains. It's comfortable between my tight teeth, even in the sensitive areas (much more so than Glide), and it almost never breaks or frays on the sharp edges where Glide broke literally every time. It cleans better in the looser spaces, too, such as under my implant. I usually had to floss 5-6 times in that area with Glide, and even then it sometimes missed things. With this floss, I only have to clean that area once or twice. On top of all that, it's gentler on my gums. I really don't know why, and I was skeptical of that claim when I saw it in other reviews, but somehow it is.

As some other reviewers have mentioned, I find myself excited to floss now. I've been flossing for many years, but it was always a chore that I needed to complete, despite the mild pain and frustration it caused. Now, it's a pleasant experience that leaves my mouth feeling cleaner and healthier.

On the environmental side, I love that there's no plastic anywhere in this. I feel good about that every time I look at the pretty container. I keep forgetting that it's compostable, so I keep tossing it in the trash and then digging it out again, but I'm sure I'll eventually adjust to that. Overall, this floss is perfect, and I'm now a lifelong convert!"

"Best and only dental floss I will use! The black dental floss is much more reliable than the white floss for some reason, just a heads up. Furthermore, the ability to reuse the old containers is an added bonus, very few products can offer both an environmentally friendly product that is also biologically inertness - especially those exposed to the vulnerable environment in our mouth."

"I wish I had heard of this product years ago! In the meantime, I’ve been flossing my teeth with PFOA— a dangerous chemical in many leading brand floss and other plastic-based products. Ugh!
The charcoal thread works really well! I thought it might be too thin when I saw it, but it’s not. I started buying this product for family and friends, to introduce them to an alternative to what we’ve been using all these years without knowing it is loaded With bad stuff for our bodies."
