Zero Waste Dental Floss: Eco-Friendly Floss for a Sustainable Dental Routine


Zero waste dental floss is not completely innocent. But flossing is important and not a dental hygiene step I’d recommend skipping. A person only gets one set of adult teeth and looking after your pearly whites should be a top priority.

Maintaining your oral health is important for a healthy lifestyle. To do this, you need to brush and floss daily. One thing that can make it difficult to maintain good dental hygiene habits is the waste created by traditional dental products like toothbrushes and flosses. But what if there was a way to eliminate the waste from these products? Maintaining your oral health should be easy with our guide on how to go zero waste when caring for your teeth!

I never gave the sustainability of dental floss a second thought. Until around a year ago when my rabbit stole a piece of floss out of the waste bin. He ran off with it and in the run ate a big piece of floss (or so we think) that almost killed him.  

For rabbits and other animals, the floss smells like mint and appear completely edible, but it’s extremely harmful to them. We’ve since bought a bathroom bin with a lid on to make sure that the rabbits can’t get to it, but wild animals don’t have the same luxury.

If you’re interested in floss picks here are a few options to consider:

Knotty Floss Bamboo Floss Picks

Packaging: Plastic-free paper box with a clear window made of some type of vegetable, not plastic

Knotty Floss was started by practising dental hygienist Elizabeth Martens from Southern California. Even though this product is almost all-natural it does contain biodegradable polyester within the floss section so is not compostable as far as we’re aware.

Packaging: Eco-friendly paper

Founded by Swedish dentist Noel Abdayem in 2013 The Humble Co. is characterised by their humble values. The floss is made from Polyethylene and the handle from Polypropylene and cornstarch so not exactly plastic-free. These are definitely less problematic for the environment than their traditional counterparts, but not entirely squeaky clean on the plastic-free front.

Reusable Zero Waste Water Floss

Water floss or an oral irrigator is a good alternative for floss and use a small pressurised stream of water between your teeth. It might actually be easier to use than normal floss and dentists do approve water flossing. Most water flossers are electric and will need to be charged or plugged in to work. Some come with a reservoir, but you also get a more streamlined cordless option.

The downside of reusable flossers is that you’ll have to dispose of the device once it breaks in a responsible way. Waterpik also recommends replacing the heads every 3-6 months. However, if you clean the heads regularly it won’t deteriorate in the same way as a toothbrush head so you should be able to use them for much longer. Just soak the tip in a bit of vinegar every 3 months or so.

Remember to de-scale your reusable flosser regularly, especially if you live in a hard water area.

Waterpik WP-660 Water Flosser

This flosser has a water reservoir, it’s a bit bulky so you’ll need the surface space to house it. It doesn’t have a battery, you’ll need to plug it in while using. It comes with 7 flosser tips, 10 pressure settings and a 650ml water reservoir which gives you more than 90+ seconds of flossing time.


Waterpik Cordless Water Flosser Rechargeable

Enjoy the convenience of a cordless water flosser to use in the shower or on the go. This option has 3 pressure settings that range from 45 to 75 PSI.

It connects magnetically to its charger, which takes around four hours for a full charge. Waterpik products generally come with a two-year warranty.


Zero Waste Dental Floss – What Are the Options?

I wouldn’t say that the zero-waste options are 100% safe for animals, but it’s at least it’s a step closer to protecting our furry friends.

Generally, dental floss is made of nylon coated in wax, or if you’re using dental tape as we did, it’s made of Teflon.

When it comes to zero dental waste floss you have a few options:

  • Regular nylon floss coated in wax but packaged in zero-waste packaging 
  • An electric water floss – this is made of plastic but does not generate waste every time it’s used
  • Vegan floss, often made from materials such as corn starch or bamboo fibres. Some of the vegan options come in some form of plastic packaging but it’s cruelty-free otherwise
  • Vegan Zero Waste Floss picks made of cornstarch. Be careful here as most of the products we researched contain an amount of plastic in the floss part. Some consisting of nylon and others of polyester. These products were also listed as biodegradable – but polyester and nylon will break down into microplastics as it’s a type of plastic. At the time of writing this article, I couldn’t find a product that’s 100% plastic-free. If you know of one, please list in the comments
  • Compostable plastic and nylon free floss that is made of silk. Unfortunately, they boil the silkworms alive to harvest the silk – not exactly cruelty-free!

If dental floss ends up in the environment, aminals won’t know the difference as they can be misled by the minty smell. But flossing remains important and should be used alongside your favourite zero waste toothpaste as you only get one set of adult teeth.

Closing Thoughts

Floss is absolutely essential so can’t be skipped, we only get one set of adult teeth and you need to look after them, for sure.

When it comes to dental floss, eco-friendly, zero waste options do still feel like the lesser of two evils to me. However, eco-friendly floss is improving and options are increasing so things are slowly taking a turn for the better.

Even if you are using a more eco-friendly manual floss like some of the options outlined above, I’d still recommend cutting it up in smaller bits before discarding it.

Biodegrading will take a long time, and it can cause damage in an animal’s gut while it decomposes. This means that if it ends up in the environment it won’t get tangled in an animals gut. It will hopefully pass through without much hassle (if we’re lucky).

Seeing animals suffer from the products we deem essential is heartbreaking, so take every measure possible to avoid causing them pain if you can.

If you do choose to use a reusable flosser like the water floss options mentioned, buy the best quality one you can find. That way it will last longer, inevitably reducing its environmental impact long term.

We have deliberately not listed any of the silk floss options as they are very cruel. Even the cruelty-free peace silk might not be as it seems. You can read more about peace silk here.


What can I use instead of dental floss?

Great alternatives to traditional dental floss is a water flosser or a floss pick.

Is there biodegradable dental floss?

Yes, many of the options on our list above are biodegradable. Look out for plastic free floss.
