Let’s talk teeth.
More specifically, let’s talk about how we all need to make some serious improvements to our dental routine by switching to a sustainable toothbrush.
Brushing twice a day and using your zero waste floss every night might make your gums healthier, but what about our planet?
The average person uses 300 plastic toothbrushes in their lifetime, equating to billions of plastic sticks finding their way to landfills each year.
But a toothbrush is perhaps the most essential of all eco-friendly bathroom products. Mouth hygiene is connected to whole-body health—and that of our planet’s.
That’s why we’re taking a bite out of plastic dental care and diving into zero waste toothbrushes.

Biting Into The Best Bamboo Toothbrushes
ZWS Essentials offers a zero waste wooden toothbrush with castor bean oil bristles which is, they say, backyard compostable—bristles and all.
For the most sustainable toothbrush offering, in our opinion, an unparalleled cleaning experience (think: 3 levels of intensity and up to 40 000 vibrations per minute) courtesy of it’s sonic technology, give Sustainable Tomorrow’s Zen Bamboo Electric Toothbrush a spin.
If you’re restocking on zero waste toothpaste, add some bamboo toothbrushes from Georganics. Their Zero To Landfill scheme makes it easy for UK customers to responsibly dispose of frayed bristles.
How We Found The Best Zero Waste Toothbrush Brands
What is an eco-friendly toothbrush? And what makes a toothbrush sustainable?
In matters of the mouth, materials matter (now there’s a mouthful).
The most popular plastic-free toothbrush handle alternative is bamboo.
Bamboo has a lot of properties that make it good for mouths (anti-fungal, antibacterial, antimicrobial) and it’s 100% compostable—even in your indoor compost bin.
It’s also one of the fastest-growing least water-consumptive plants and, once it’s harvested for toothbrushes, it can continue growing because harvesting doesn’t kill the core plant.
Bamboo may be the best sustainable toothbrush for now, but we’ll see how the industry continues to evolve. For example, recycled and reusable aluminum handles paired with a compostable toothbrush head would further eliminate waste.
However, to make a bamboo toothbrush zero waste in every way, we have to consider the bristles, too.
The Challenge Behind Zero Waste Toothbrush Bristles
Now we get to the real complication in the world of eco-friendly toothbrushes: bristles.
It’s not too difficult to have a biodegradable toothbrush as far as the handle is concerned, but bristles often get in the way of a toothbrush being fully compostable.
Also, remember that nearly all materials (even if they’re made of plastic) will technically degrade after some time, but oftentimes it takes hundreds of years.
Compostable materials are biodegradable, biodegradable materials aren’t necessarily compostable. Pretty simple concept, right?
Well, not for some brands who fall a bristle short and confuse the two and end up greenwashing.
My Plastic Free Life did some extra brushing (in a circular motion, of course) to discover supposedly “biodegradable” nylon bristles were in fact not biodegradable.
So what’s the best way to brush?
Well, we really only have a few “zero waste” toothbrush options:
1. Boar bristle toothbrushes:
Boar bristles would yield the only undoubtedly compostable toothbrushes currently available to us—but brushing our teeth with pig hair sounds like the worst way to get a fresh and minty mouth.
2. Castor bean toothbrushes:
While castor bean (AKA Ricinus communis) is a flowering plant, the bristles made out of it aren’t always as wholesome as they might sound.
Nylon-11 is what you get when you subject castor bean oil to a complex (and chemically intensive) process. Its biodegradability is still up in the air.
Some brands claim their castor bean oil bristles are home compostable, some state they’re industrially compostable, and some still place them on the list of what not to compost and recommend recycling. We’re inclined to err on the safe side and agree with the latter.
3. Miswak sticks:
This traditional oral care tool was popular in Pakistan, India, and parts of Asia and Africa. Studies show that it’s as effective (or perhaps superior) to other types of toothbrushes.
You can find several sellers for these organic chew sticks on Etsy.
Final Thoughts On Sustainable Toothbrushes
Feeling like you have a potty mouth after reading this?
Toothbrushes, like most consumable these days, are notoriously damaging to the health of our planet.
And zero waste toothbrushes—like the rest of the zero waste philosophy—aren’t quite literally zero waste. They’re just one of those things where we simply have no choice but to accept that caveat of imperfection.
But there is a shimmer to be found in our smiles; we’re getting closer to having a fully vegan and compostable toothbrush thanks to these bamboo toothbrush brands.
If you’re still wondering, “How can I make my toothbrush more sustainable?”, try to reuse your blown out brush for zero waste cleaning before retiring it altogether.
Then have your pliers at the ready to remove those burdensome bristles for proper recycling.
