What is a Zero Waste Toothbrush?

A zero waste toothbrush is a toothbrush that is designed to create little to no waste. Regular toothbrushes are often made of plastic and have to be replaced every few months, which can lead to a lot of waste. In contrast, zero waste toothbrushes are made from eco-friendly materials that are biodegradable or recyclable.

Why Choose a Zero Waste Toothbrush?

Did you know that over a billion plastic toothbrushes are thrown away in the United States every year? That’s a staggering amount, and if you were to lay all those toothbrushes end-to-end, they would wrap around the Earth four times! 

Choosing a zero waste toothbrush is an easy way to reduce your environmental impact. By using a toothbrush made from sustainable materials, you can help reduce the amount of plastic that ends up in landfills and oceans. Additionally, many zero waste toothbrushes are designed to be more durable than regular toothbrushes, which means they can last longer and reduce the need for frequent replacements.

Types of Zero Waste Toothbrushes

There are several types of zero waste toothbrushes available, each with their own unique benefits.

Bamboo Toothbrushes

Bamboo toothbrushes are one of the most popular types of zero waste toothbrushes. They are made from bamboo, a fast-growing, sustainable material that is biodegradable. Bamboo toothbrushes usually have nylon bristles, which are not biodegradable but can be recycled.

Stainless Steel Toothbrushes

Stainless steel toothbrushes are another popular option. They are made from durable, rust-resistant steel and often have replaceable silicone bristles. Stainless steel toothbrushes can be recycled at the end of their life, making them a great option for those who prioritize recyclability.

Biodegradable Plastic Toothbrushes

Biodegradable plastic toothbrushes are made from plant-based materials, such as corn starch or cassava root. These toothbrushes are designed to biodegrade over time, reducing their impact on the environment. However, it’s important to note that they still require industrial composting facilities to break down properly.

Corn Starch Toothbrushes

Corn starch toothbrushes are similar to biodegradable plastic toothbrushes, but are made from corn starch specifically. They are biodegradable and compostable, making them a great option for those who want a truly zero waste toothbrush.

Choosing the Right Zero Waste Toothbrush

When choosing a zero waste toothbrush, there are a few factors to consider.

Bristle Options

First off, let’s talk about bristles. There are two main types: nylon and plant-based. Nylon bristles are the most common, but they’re not biodegradable. Plant-based bristles, on the other hand, are made from materials like bamboo or castor oil, and they’re completely compostable. Plus, they’re just as effective at cleaning your teeth as nylon bristles! So, when choosing a zero waste toothbrush, I highly recommend going for plant-based bristles.

Handle Design

Next up, let’s talk about handle design. This might seem like a minor detail, but it’s actually really important. After all, you’re going to be holding this thing in your mouth twice a day (hopefully!), so it should feel comfortable and easy to grip. Some zero waste toothbrushes have a sleek, minimalist design, while others have a more ergonomic shape. Personally, I prefer a toothbrush with a little more grip, but it’s all about personal preference.

Considering the Price

Of course, price is also a consideration. Zero waste toothbrushes can range from a few bucks to a bit more expensive. But, it’s important to remember that investing in a high-quality toothbrush can save you money in the long run, since you won’t have to replace it as frequently. Plus, you’re doing your part to reduce plastic waste and promote a more eco-friendly lifestyle!

Top 6 Zero Waste Toothbrush Brands to Try 

If you’re on the hunt for the best zero waste toothbrush, then it’s crucial to pay attention to the brand you’re buying from. I’ve personally tried and tested a bunch of toothbrush brands that are dedicated to reducing their environmental impact and making toothbrushes out of sustainable materials like bamboo or recycled plastic. So, based on my personal experience, here are my top picks that you definitely need to check out!


EcoRoots is an eco-friendly toothbrush brand that aims to reduce the number of plastic toothbrushes that end up in landfills each year. They offer a sustainable alternative to traditional plastic toothbrushes, with a 100% compostable bamboo handle that is anti-fungal, anti-bacterial, and antimicrobial. The toothbrush bristles are made of soft nylon that is BPA-free and non-toxic. Plus, the bristles are infused with activated charcoal for whitening benefits. Although the bristles are not compostable, they can be recycled through TerraCycle.

EcoRoots is dedicated to sustainable packaging and ships toothbrush sets in plastic-free packaging. The brand is based in Colorado and is certified cruelty-free by Leaping Bunny. They are committed to helping customers make their homes plastic-free, from toothbrushes to toilet cleaning products. They use only recyclable and compostable materials for their shipping, and they have donated almost $14,601 to the Ocean Conservancy to date.


Greenzla offers an eco-friendly dental hygiene kit that includes 4 bamboo toothbrushes, dental floss, and a toothbrush case for easy storage and travel. The toothbrushes and packaging are biodegradable and compostable. The charcoal-infused bristles are soft on teeth and gums and help remove stains.

The brand uses only responsibly sourced natural materials that are additive, coloring, and BPA-free, making them better for you and the planet. Even their packaging is recycled and biodegradable.

The best part about this toothbrush is how sustainable it is. The handle is made from renewable timber that feels so comfortable in my hand, and the plant-based bristles are biodegradable and recyclable. So not only am I taking care of my teeth, but I’m also taking care of the planet. Win-win!

And let’s talk about the brush head – it’s huge! The wider brush means more bristles and more surface area covered at once, which makes for a great cleaning and a soothing massage of my gums. I can even reduce the risk of gum and heart issues by massaging my whole mouth. Who knew brushing could be so relaxing?

Overall, I highly recommend the RADIUS Big Brush toothbrush. It’s sustainable, effective, and just plain fun to use. Plus, with a name like “Big Brush,” you know it means business. Give it a try and see for yourself – your teeth (and the planet) will thank you!


I highly recommend the Preserve Eco Friendly Adult Toothbrushes to anyone looking for a sustainable and effective oral care solution. The handles are made from 100% recycled #5 plastic, while the bristles are made of new nylon. Plus, the packaging is made from 100% recycled content and is recyclable after use, which is a huge bonus.

But not only are these toothbrushes eco-friendly, they also work wonders for my teeth and gums. The curved handle is easy to grip and allows me to reach all those hard-to-get places, while the tiered bristles provide a thorough yet gentle cleaning. And the fact that they come in a 6 pack with assorted colors is just the cherry on top.

It’s also worth mentioning that Preserve is a small business brand, which makes me even happier to support them. 


These toothbrushes feature soft bristles made from 100% castor bean oil, which is a plant-based alternative to traditional nylon bristles. Although the bristles are not compostable yet, I appreciate the effort to move towards sustainable materials.

One unique feature of these toothbrushes is that they can be separated into two parts, making them handy for travel. However, I was disappointed to learn that replacement heads are not available because Bite hasn’t found a way to make them without producing a separate handle.

But don’t throw away the handle just yet! Before composting it, Bite suggests downcycling it to clean hard-to-reach areas like grout or compost keyboards. I love that they’re encouraging us to make the most out of their product. You can order a two-pack of these toothbrushes as needed, or sign up for their subscription service to save some money.


If you’re searching for a toothbrush that’s not made of bamboo, the Georganics beechwood vegan toothbrush, made in Germany, could be your answer. This toothbrush is constructed from beechwood, sourced from sustainably managed forests that have been certified by the Forest Stewardship Council. The bristles are made of BPA-free nylon and come in soft, medium, and firm sizes. Additionally, the head is easily snappable, making it convenient for replacement.

The handle is compostable, and if you live in the UK, the company provides a Zero to Landfill program. You may send the snapped-off toothbrush head to the company, and they will recycle it for you via their partnership with recycling company TerraCycle. Furthermore, there is a kid’s size toothbrush option available as well.

How to Take Care of Your Zero Waste Toothbrush

Now, let’s talk about caring for your zero waste toothbrush. To make sure it lasts as long as possible, rinse your toothbrush thoroughly after each use and store it in a dry place. Don’t store it in a closed container, as this can lead to the growth of bacteria. And, when it’s time to replace your toothbrush (usually every three to four months), be sure to dispose of it properly. Some zero waste toothbrushes can be composted, while others need to be sent to a special recycling facility.


In conclusion, choosing a zero waste toothbrush is a small but impactful way to reduce your environmental impact. By opting for a toothbrush made from sustainable materials, you’re helping to reduce plastic waste and promote a more eco-friendly lifestyle. So, the next time you’re in the market for a new toothbrush, consider going zero waste! Your teeth (and the planet) will thank you.
