Zero Waste Dental Floss

One of the questions I get asked most when it comes to dental hygiene is about the floss I use and what I can recommend. Pretty much everybody who is interested in Zero Waste knows about bamboo toothbrushes, tooth powder and homemade toothpaste. However, when it comes to dental floss most of us are at a loss.

Regular dental floss is just waxed nylon, rolled up in a small plastic box. Just like plastic, nylon is derived from crude oil. Unlike plastic, it does not take 500 to thousands of years to decompose, but “only” 50 – 80 years. #notimpressed

When you are vegan like I am, or you try to find a cruelty-free option when it comes to cosmetics and toiletries, then you will be at a loss here. The options are grim: The floss is either compostable, nylon- and plastic-free, but not vegan, because it is made from silk, for which silk worms are boiled alive. The vegan options are all made from nylon, in which animals might get caught and most likely die a gruesome death.

So here are your options, yay…

Silk Floss (Radius)

Radius is probably the best-known brand. You can find them at Whole Foods and other health food stores. However, even though they seem to love to advertise how “Good for the earth” their floss is (“Not only is our floss 100% vegetarian, it’s also 100% biodegradable”), they still don’t mind putting their floss into a plastic case. On the package I could find information on the floss (biodegradable in 60 – 90 days), on the paper packaging (recyclable), but none whatsoever on the plastic container. As if it didn’t exist.

Anyway, they also sell their floss in sachets, which I fand rather wasteful. I wasn’t able to open the package to check as to what kind of material the sachets themselves are made of. Seems like they are plasti-free at least, I remember something on the packaging stating “100% biodegradable packaging”. Still, not impressed.

The price was steep compared to regular floss (30 m for £3.90), but OK when you think about the fact that it’s silk, a material generally more on the expensive side.

Radius also sells vegan floss, but it’s nylon and comes in the plastic case. So no real gain there compared to regular floss.

Silk floss with beeswax (Vömel)

Zahnseide Vömel

The German manufacturer Vömel sells their silk floss in a tiny, yet very classy vial. Their products are usually packaged in another layer of plastics, but if you order the floss at the German online store monomeer.de you will be able to to buy it plastic-free, because Monomeer sends Vömel paper bags to use instead of the plastic packaging. I also found the floss in the newly opened Zero Waste online store called Zero Waste Laden. The store was opened by the Zero Waste Blogger Olga and her husband Gregor.

Bad news is, both online stores are in German (I’m sure Google Translate can help though), and I don’t think they offer an international shipping option. However, I know that monomeer has a great customer service, and I’m sure as true zero wasters Olga and Gregor will be thrilled if you show interest in their products. And if you ask nice, they might send it abroad. The two years worth of floss I ordered fit into a single envelope, so it also shouldn’t cost a lot.

The floss itself is a bit pricey. 10 m with vial cost 3.95 € (= £3.14 or 4.46 US$). 2 x 10 m without the vial are 4.90 € (£3.89 or 5.53 US$).

Unravel a piece of silk fabric

Béa Johnson’s go-to method, is to unravel a piece of silk fabric, twisting a couple of threads together, and to use that to floss.

Update: I was just told that there is at least one producer of “peace silk” who lets the silk worms hatch! So if you can get your hands on a piece of peace silk, that might be a very eco-friendly option that might or might not count as vegan, also depending on your motivation for being vegan.

Vegan floss without a plastic case (Ecodent)

I contacted Ecodent a couple of months ago, because I couldn’t find any information on the material and whether or not their floss was biodegradable. Their live-chat customer service agent was unable to answer my question, and when the reply to my email arrived, what it said was: “We have not tested the floss for the amount of time it would take to biodegrade but I did find on-line that dental floss can decompose in 1-5 years.” I mean, seriously??

So I googled “How long does it take for dental floss to decompose.” The very first hit said 1-5 years in the preview. I clicked on the link, that led me to some handout for some summer camp. Right in the list it also said a plastic bag needs only 20-40 years to decompose, instead of the usual number in the hundreds. Somebody really went out of their way to find some reliable information.

Well, it is true that they use cardboard packaging, don’t have a plastic case, and provide 100 yards (91.44 m), but they failed to mention that there is another plastic wrapper inside the cardboard packaging, and that there is also 2 plastic stickers on the outside.

At least it is really affordable with only 5.49 US$ for 100 yds.

So what is the right decision when you live vegan and zero waste?

I’m afraid there is no right answer to that question. It’s the choice between boiling silk worms alive or something derived from crude oil that might also end up strangling animals. Great.

I really don’t get it. In Europe there are already bamboo toothbrushes with nylon4 bristles that do decompose within 18 months! You can even compost them in your yard or wormbin! Why don’t they use it for dental floss?

I have tried cotton threads, but they tear really easily, even when you twist multiple threads together.

Last year I saw this photo online that I couldn’t get out of my mind. Nylon threads look so benign, but they are tear-proof which is a huge problem.

 

(More here 😢)

After seeing this photo I decided to order the Vömel silk floss, even though they are clearly not vegan. At least this way I’d know where the floss will end up – which is in our very own worm bin along with our kitchen scraps.

So I decided to place a collective order and decided to get enough floss to last me two years.

Only later did I find out that in Germany (where we live) waste does not get landfilled anymore! If it cannot be recycled, it will be incinerated. (Find out more about what happens to the trash after collection here) So as long as you don’t recklessly toss your floss away, it will not end up somewhere where it will be able to hurt animals.

I’m still not sure what I will do next year when I will have used up the silk floss. I’m still hoping that some vegan, cruelty-free and biodegradable dental floss with no plastic case or other plastic packaging will miraculously pop out of nowhere, falling right in my lap.

Well, and if not… Well, than I guess I might have to give flossing with hair a try. Well, pre-historically humans are said to have used horse hair to floss their teeth. And in the end, when you think about it, it is not really more absurd than using fibres that came out of the butt of a worm, coated in bee discharge to floss…

  1. Hello :)!

    I have a comment on using horse hair as floss :D…. I have a horse – an icelandic – and when I am at the stable and got something stuck in my teeth I always “borrow” (not using a scissor or something, just use the hair while it is on the horses tail) one of her tail hair to floss (already got some weird faces from stable colleagues for that :D) and I would say that it works better than any floss available on the market :)….. Just the right texture and feeling…. (want to add that I shampoo the tail regularly!!! so it is not disgusting at all 😀 )
    So now that I have seen this horrible photo of the poor seal I am seriously thinking about cutting some of my horse tail hairs and use it as floss when I used up my Gentle Floss (my horse is an icelandic, she has lots and lots of tail hair, she want miss it :)…)

    I am aware that this comment does not really help you because you do not have a horse buddy waiting to give you some of his or her hair to floss, but I just wanted to mention it :)….

    All the best, have a nice day!

    • Hi Franzi! It’s really cool you have a horse! I’d have killed to have one as a kid lol! Well, do go for using it as floss! I know I would if I had a horse ;)! Btw, I have tried my own hair, but even twisting multiple (of my really really thick black Asian) hairs they tear almost instantly :(. Some readers on the German version of my blog have recommended thicker tear-proof cotton threads and it works for them. However, when I tried they were too thick. And when I untagled the thick thread into 3 thin ones and used these, they also tore almost instantly. I guess the gaps between my teeth are just too narrow? I have put coconut oil on the thin thread, but it didn’t work. When I put on beeswax it didn’t tear as easily, but still tore quite often. Sighs, I’m not really sure I want to continue using beeswax though. I’m vegan and it’s not a long-term solution for me. Oh well XD… #zerowasteproblems right ;)?
      Have a great weekend!

  2. Hi! I’ve heard that oil pulling everyday works great and that you don’t need to floss anymore after that. Why not try this? 🙂 I personally rarely floss -which is not very good- but think that then the one time you get something really stuck in between you teeth, you can then either use your own hair or a wooden toothpick? If you oil pull regularly, of course!

    Thank you for all the information and research! I love your website

    • A lot of people have recommended oil pulling to me actually :D. I want to give it a try, but since I have had severe gum issues I don’t think quitting flossing is an option for me. As my dentist has explained, 40% of our teeth’s surface can only be reached by flossing. Not mouthwash, and probably not oil either. But I will definitely give it a try, just not as a substitute for flossing :). Thanks!

        Sesame oil penetrates the teeth right into the bone and prevents cavities and gum disease. Ayurveda advises swishing it in the mouth for several minutes each morning.

  3. Thank you for this awesome post, I will definitely be sharing this with my friends who refuse to accept that something as tiny as floss can cause that kind of damage to animals and the environment I recently started using the radius brand silk floss, and it comes in a little cardboard box so they must have changed their packaging? The sachets inside are anoying because it kind of turns it into a single use item, but they are compostable at least. Next time I’m in Germany I want to order some of the vomel kind!

    • Especially small pieces of plastic can be very harmful! Microbeads for example:

      Radius silk floss comes either in a plastic case or in these ridiculously wasteful sachets :(…

  4. Losing my natural floss was the main reason it took me so long to cut my hair . I thought it was so convenient to run my fingers through my hair and get “floss” from my hair that would have simply fallen out on its own. Now that I have short hair, I’m still on the search for the best option here in the states. I’ve been eyeing my mother-in-laws hair, long Japanese hair would be perfect to use… But she doesn’t get my ZW efforts and would probably be grossed out if I asked her for some strands haha.

    • LOL, I’d LOVE to see your mother-in-law’s reaction XD! I have really thick Asian hair too, but seems like there isn’t enough space between my teeth. Even twisting multiple hairs they tear almost instantly when I try to use them to floss… Or maybe you have a friend with a horse ;)?

  5. Why don’t you purchase a Philips air flosser?
    It’s small and easy . I realize that it is made of plastic
    But it lasts a long time . Then you won’t need to floss . I’m a dentist who is also in search of a
    Compostable floss with compostable packaging
    .

  6. The picture of the seal that was heartbreaking 🙁 Was that floss that was wrapped around the seals neck? What if I cut the floss string into small pieces until I’m done with it and then I want to try stim u dent picks. Have you heard of them, their little sticks used as floss and there vegan, also have you tried the miswak toothbrush which is made from a tree.

    • Hey Nicole,
      I don’t use dent picks since I can’t get these between my teeth. You can of course cut the floss, but either way – plastic in the ocean is a bad idea. I have a miswak twig but also a bamboo toothbrush :).

    We have the Radius floss, but I was thinking about the plastic container while using it this morning and a quick search brought me here. I think animal hair would be a great option, if I knew where to et some, lol.

    I also wanted to share my oral hygiene routine that I started about a week ago. It really works for me. Instead of using a toothbrush, which holds onto a lot of plaque-causing germs, I scrub my teeth with a washcloth. 100% cotton cloths are easy to find, and I can wash it however often I feel the need. I’ve noticed, because I’m not sticking the same bacteria back into my mouth every time, my teeth build up plaque more slowly. I use the edge of my cloth, which is thicker with stitching, to get the tops/bottoms of my molars. I want to add oil pulling to my routine, but haven’t yet, and I find that flossing is still the best way to get between the teeth.

    Maybe this is a silly idea or too simple to work– i am going to test it out and see– and please tell me if you have tried it yourself: what about buying the most durable vegan floss and reusing a strand of it repeatedly by disinfecting in with a simple, enviro-friendly agent like vinegar. I feel awful about using my floss now that i just discovered it is teflon, but since i already have the product, maybe i can take its longevity to new extremes. If you find any new ideas please keep posting. Peace and love, packaged only in 100% compostable human.

  10. Hello From Australia!

    Oh dear I didn’t realise a lot of rubbish in Germany gets incinerated! that cannot be good for the environment!

    Is Ecodent floss made of nylon?

    • Hey Sarah,
      yes, Ecodent floss is made of nylon. I even emailed them and asked if they could tell me how long their nylon takes to decompose. They told me they do not know :(. And yup, a huge part of our trash gets incinerated. It’s better than landfills and at least it prevents plastic from ending up in the ocean (landfill trash very often gets blown into rivers), however, it is still very far from eco-friendly…
      Warm regards from cold, cold Germany lol,

  11. I am also looking for alternatives for dental floss but I couldn’t find a more organic one here in my country (Philippines). But then I discovered this portable water flosser, called Pocket Flosser, in Kickstarter and I think it’s a great alternative! Water flossers works just as good, or even better, than dental floss. It’s basically water pressure pushing food debris (and even plaque) off. What’s great about this is that it doesn’t need any electricity or even batteries so you don’t have to worry about energy. It only requires easy manual hand pump to accumulate pressure then it’s just as good. While this doesn’t necessarily fit in your pockets (as the name may suggest, the pocket actually refers to spaces in between the teeth), I still think it’s a better alternative to those pricey and stationary water flossers, and it’s very still handy when traveling. While the pump may be made in plastic (the developer didn’t specify the exact material), at least it’s BPA-free. It’s also better because it’s only a one-time purchase and you don’t have to worry about running out or disposing anything. 🙂

    If you love this product, you can get them here and help the developer produce this awesome invention:

  13. What about…
    RADIUS
    Vegan and Biodegradable Floss Sachets with Natural Xylitol, Mint, 10 Count
    ?
    It says it’s both vegan AND biodegradeable. I haven’t ordered it yet. I’m not sure if the packaging is eco friendly.

    • Unfortunately it is only the packaging that is biodegradable and not the floss itself, which is nylon.

  14. I was shocked when I saw the poor seal, and couldn’t take my eyes off the poor little guy – then I realized, that can’t possibly be floss – it’s way too thick – not to mention incredibly long to be able to do that. Hope that might be a (sort of) comfort to some,. I doubt flossing is hurting animals like this – but the garbage is.

    I hope everyone remembers to check with their dentist in regards to any diy floss, just to make sure they’re not hurting their gums. Otherwise, may as well not floss. Thanks for the post.

  18. Hi there,
    I bought silk floss in biodegradable packaging when I lived in France 5 years ago. I’m now back in my home country of Australia, and just starting searching online for a replacement (While I’ve been using a nylon floss I accidentally acquired, I clearly don’t floss enough). I sadly tossed the packaging from the packet I had a year or so ago, without noting any details, thinking I’d just hop online and replace it. I can’t find that brand in particular, however if you’re willing to forgo the no-silk rule, but have biodegradable packaging, I have two options that might interest you!

    Thank you for this article! It is heartening to know that someone shares the same ethical struggles as I do! I think maybe a good option is to cut the floss after using it. It wold probably be fairly easy to wind it around your fingers and make one cut across multiple loops thereby making the floss into several pieces too short to get tangled around an animal. Still not perfect because the pieces could still end up in the digestive tract of an animal.

    I read an article about peace silk and ahimsa silk and it’s still not a perfectly ethical option.
