What is the most sustainable toothbrush?

A scientific study uncovers the truth about oral care sustainability

The first ever scientific studyto quantify the environmental impact of toothbrushes was published in theBritish Dental Journal in 2020. Here is what they found…

Environmental and human impact studied

Researchers at Trinity College Dublin,in collaboration with Eastman Dental Institute at University College London, performed alife-cycle assessment (LCA) study on the sustainability of toothbrushes.

Their goal was to ascertain which kind of toothbrush is best for the planetandhuman health.

Which toothbrushes were compared?

Researchers considered different manufacturing models and measured the environmental impact (carbon footprint) and human health impact (Disability-Adjusted Life years or DALYS) of the following toothbrushes: Electric toothbrush, Plastic (disposable) toothbrush, Plastic toothbrush with replaceable head and Bamboo toothbrush.

The losers

Not surprisingly, the disposable and electric toothbrushes did not do well in the study. In fact electric toothbrushes proved to be 5 times worse than disposables for planetary and human health, mostly due to the manufacturing process.

The most sustainable toothbrush is…

This might come as a surprise to some, but bamboo toothbrushes arenotthe most sustainablemainly due to the land and water requirements needed to grow bamboo.

Thebest toothbrushis a toothbrushthat uses plastic which is recycled in a continuous process.

From the lead researcher:

“We have also shown bamboo toothbrushes are not the answer. Using them just stops land from being put to better use such as helping biodiversity, or in growing forests to offset carbon emissions.

There are billions of toothbrushes used and discarded every year. Our research shows that electric toothbrushes are actually harmful for the planet and to the people involved in the manufacturing process and distribution.

There is not a lot of evidence to show they are more effective unless you struggle to clean your teeth with a normal toothbrush.”

Dr Brett Duane,Lead Researcher and Associate Professor, Public Dental Health, Trinity College

The article also states: “We need a system where plastic toothbrushes can be collected like batteries and then recycled into new products.

While the study called it a “hypothetical toothbrush,” it exists.

Dental Gold!!

As a person who has worked in the dental field for 16 years, I have seen many different types of toothbrushes and tried them all. The Nada toothbrush is probably the best I have seen so far. A lot of toothbrushes on the market have flat bristles, and they do not get Into the gingiva like a tapered bristle should. I love how eco-friendly they are and I am very happy with this purchase. I am trying to turn all of my friends onto this product!

Only sane and sensible choice, and a great toothbrush too!

In a planet in jeopardy, the only sane choice is non-disposable. And when you have an option like this superb toothbrush that does not put a plastic handle into the land fill every couple of months, it’s a no-brainer….

I switched from disposable razors a few years back, using a retro double edged razor that replaced only the blade and comes wrapped in a sliver of paper. Now, the toothbrush equivalent is here and there is no reason not to use it, as it is a wonderful brush.

Really great

This little life improvement is beautifully made and all it claims to be. Love that the head is recyclable and that the handle can be an heirloom….it’ll last forever.

Totally Impressed. What a find!

Started using my Nada after visit to hygienist and that same sense of totally clean teeth has been maintained. Subsequent visit with hygienist confirmed - what an excellent tooth brush! Gums happier. Teeth so clean. Super design. Fantastic weight in the hand. Love the tongue scraper too. So impressed. And its environmental benefits are just icing on the cake! Already purchased/given several as gifts and have a few on hand as stand-bys to give away...maybe! Very happy to promote and support such a great product. Love my Nada! Thanks!

Best toothbrush ever

I've been using a Nada toothbrush for a few years (since they were Grin), and it's the best brush ever.
The bristles are softer and smaller than nornal bristles so my teeth feel cleaner. Flossing is faster because the bristles get between my teeth better than disposable brushes.
The handle is great because it has no grooves to collect gunk, and it doesn't tip over and get toothpaste on the counter.
The whole thing fits my mouth and my hand better.
This is one of the best purchases I've ever made.

Surprisingly superior clean

We replaced the whole family’s toothbrushes with Nada’s. I love the colours and the heft of the handles, but was surprised by how much cleaner my teeth felt after brushing with these soft bristles. So I’m pleased that the environmentally superior choice is also a superior product. AND it’s not more expensive! Win-win-win.

Exceeded all expectations

Sleek looking! There is something about owning and keeping this toothbrush rather than just buying, using and disposing of a toothbrush. Makes you want to take care of it and be proud of something that you use and will continue to use everyday.

The Perfect Toothbrush Does Exist!

I got my husband and I both a Nada toothbrush for our Christmas stockings, and we are both BEYOND happy with this product! My husband loves the weight of the handle while brushing, and I love how sleek the design is (meaning it's easy to keep clean, which means much less bacteria growth!).

But most importantly, we both love how easy it was to change out our old brushes to this sustainable eco-friendly option. We've been working hard as a family to reduce our plastic waste, and researched hard for an alternative to our plastic toothbrushes - and Nada has proven to be the perfect addition to our daily routine! I cannot recommend this brush enough.

Plus, as Canadians, we love supporting Canadian businesses 🇨🇦 A win for the environment, and a win for supporting a local business - we love it!!

The best toothbrush !

We love our Nada toothbrushes. We have tried all kinds of toothbrushes in our search for an alternative to the plastic status quo toothbrushes and Grin ( Nada) has come up with the best system yet and they do a great job of cleaning your teeth and they look so sleek in your bathroom. Not only that but Nada is a small company and I appreciate the personal responses I have received to my questions. Yay Nada !

Exceeded Expectations

I was excited to give these a try, the idea behind it is great and I was hoping to at least appreciate the experience. In reality, I love it and I'm never looking back. I also got one for each family member, and they too use it exclusively. The design is fantastic, it really feels like a premium experience, but without the guilt of harming the environment. My favourite part is the weight and balance of the handle. It's all incredibly affordable and easy too, I'm excitedly counting down the days I can send my brush tops back for recycling. Knowing it's a local Canadian company is also always a huge plus. I highly recommend this to anyone who is on the fence. At least give it a try, you will not regret it.

Best toothbrush EVER

I recently purchased a Nada toothbrush. After having tried other replaceable-head toothbrushes with various levels of success, I am thrilled to report that Nada exceeded my expectations. Its smooth metal handle feels great in the hand, the length is perfect and the head is just soft enough to be gentle, yet do a great job. The fact that the company takes back the heads to recycle them was one of the selling features for me. This is a purchase that helps the environment while providing the user with excellent value. I would highly recommend it!

Love it!

I love my Nada toothbrush. The bristles are gentle, AND effective. I get a way better clean than with my old, disposable toothbrush. And I love the metal handle. So sturdy, and I can clean it! No gross nooks and crannies.

Very happy

Our family switched to these toothbrushes a month ago and we love them.
A long-lasting aluminum handle, replaceable soft heads that get recycled by the manufacturer, and that warm feeling of saving the planet while you save your teeth ... priceless!

I love the upgrade!!

I was already in love with the Grin toothbrush and when I tried to order my brush head replacements, I was surprised to see that Grin is now Nada.

The new models have a tongue cleaner and that's all it took to convince me to replace mine and my husband's Grin brushes with Nada. These toothbrushes are a much better, environmentally conscious choice and the best part is that my dentist is surprised by how well the toothbrush cleans. You've found a loyal customer in me, Nada :D
