Over 3 billion disposable toothbrushes are thrown out every year. So we made Nada — the sustainable toothbrush people love.
Dr. Richard Rapoport, Dental Surgeon, MAGD
Great toothbrush. Love the feel of the bristles and they last a long time. I enjoy using my Grin more than my Oral B rechargeable toothbrush.”
Dr. Paul Sirek DDS
Amazing toothbrush! I love the feel of the bristles and the design of the handle. I definitely recommend this product!”
Melissa, Registered Dental Hygienist
As a dental professional, it’s hard to find a product I actually like knowing the science behind certain components but this brush checks off all the boxes.”
Kristen, Registered Dental Hygienist
I've been brushing with Grin for 6 months now and have since retired both my bamboo brush and Sonicare Diamondclean. My teeth have never felt this clean with any manual or electric brush!”
Heidi Collins, RDH
I’m a dental hygienist and had been urged to try your brush by a patient. I love it. First of all the design is sleek and the handle is so comfortable to hold and super stylish. I love the brush head length and softness of the bristles. Thanks for creating this awesome toothbrush. I love it.”
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
I was skeptical when I ordered our first Grin Toothbrush handles and heads. I brush my teeth 3 times a day and I am hard on my brush heads (I am gong to be 50 years old this year and I have never had a cavity!). With high-end disposable toothbrushes, I need to replace them every month because the bristles get quickly worn out and splayed, so when I read that Grin recommends changing them every 3 months, I thought, "Yeah, right!" Well, I am thrilled to say that after 3 months of use, my Grin Toothbrush heads are only just beginning to show signs of wear, and barely. The toothbrush base handles are attractive and comfortable to hold, and I love that I can replace the heads every 3 months. I love that I can help the environment by not adding a disposable toothbrush to our landfill every month AND I am saving money!
What is not to like about this toothbrush — the design is absolutely perfect! The handle is comfortable and easy to hang on to, even with wet hands and when brushing vigorously. (I sure can’t say that about other toothbrushes.) The head of the toothbrush is just the right size and configuration to reach all areas of the teeth and tongue, and while the bristles are soft, they are still incredibly effective. To cap it all off, when those bristles wear down, I’ll just be replacing (and recycling) the small head, not throwing out a big piece of plastic, as one does with regular toothbrushes. Both my husband and I are pleased to bits with our new brushes, and we’ll be spreading the word!
The soft bristles, the subscription, and the recyclable heads are excellent. You have to replace your toothbrush every 3 months and so many people don't realize this and the subscription helps you make sure you do that. The soft bristles are safe for use on the gums they won't cause so much damage if you're brushing too hard. Overall I love my grin toothbrush and I would recommend it to anyone. If you think the bristles are too soft because your teeth aren't clean you're probably not brushing long enough make sure you do it for a full 2 minutes not 30 seconds. ;P
My dental hygienist noticed the difference right away, as did I.
Not only saving the planet, Grin Toothbrush is a fantastic way to clean your teeth!
I gave it about a month after buying these toothbrushes for every member of the family to really test them out. We LOVE them! They clean better than electric toothbrushes we have used in the paste, love the weight and feel of the handle and the soft bristles, and I love the eco-friendly sustainable design. I try to support Canadian companies wherever possible and this company is so worth supporting! Keep up the great work guys!!
Honestly, I wasn’t expecting much. I wanted a more eco friendly option for my toothbrush, and this was Canadian and seemed decent. I am thoroughly impressed. It’s honestly the best brushing experience I’ve ever had.
I *love* this brush!! I bought one for myself and one for my husband and we are both Grin-ing! I liked the eco-focus but was worried the quality of the brush would be compromised for a cool "gadget" - boy was I wrong!! The quality of the bristles is excellent - the bristles are soft but the shape allows for a truly superior clean. The weight of the handle adds comfort, and the shape brilliantly prevents rolling on countertops and sink edges. AND eco-friendly with an easy recycling program, and it's beautiful - and who says that about a toothbrush? I honestly cannot say enough good things, I didn't think I could like a toothbrush so much - well thought out and expertly executed! My experience with customer service couldn't have been easier or more pleasant. Seriously, am I gushing yet? Very impressed and would most highly recommend in literally every aspect.
I love this toothbrush. Was nervous after switching from my electric toothbrush, but I’ve been so happy. The brush head is long and gets behind your molars, and the bristles hold up way better than other toothbrushes!
I've been using my Grin Toothbrush for over a month now and I must say that my teeth actually feel cleaner. I didn't think it was possible to love a toothbrush this much but alas I do. I love the rose gold colour, the soft but durable bristles, the aluminum handle, and the concept behind the Grin Toothbrush. I purchased the subscription for myself and my husband and have yet to replace our brush heads or send them away to be recycled but I'm happy that I've found a zero waste alternative to our former disposable toothbrushes. I love using such a luxe toothbrush and the positive impact that it has on the environment. It's a win-win!
I have been using my grin toothbrush for almost a year and I'm so happy to have made the switch from a standard toothbrush. I have since ordered replacement heads and have been enjoying how easy it is to replace the heads and collect used ones to be recycled. 10/10 would recommend!
These toothbrushes are amazing. I bought the subscription for myself and my husband, and our toothbrushes arrived within a week of ordering, along with over a year's worth of replacement heads. The handles are beautiful and the experience of brushing feels as good as conventional toothbrushes (and much better than the alternative, eco-friendly bamboo toothbrushes we had before). This is such an awesome business model - every day, when I brush my teeth, I'm reminded that even the smallest, most routine decisions can have a major impact on our planet. Thanks Grin! :)
I'm in LOVE with my new toothbrush! It cleans just as well as regular toothbrushes but it feels so great knowing that I'm reducing my plastic waste by using a metal toothbrush. The best feature is the head being slightly elevated so that it doesn't touch any surfaces. I highly recommend!
Love this product. The gorgeous aluminum handle is nicely weighted in the hand and the bristles are soft. Perfect. I bought the one with five heads so it is a cinch to switch heads after three months- they even email you a reminder. Worth everything penny and some it does to charity too.
There’s nothing I don’t like about these! They do a great job cleaning - my husband just went to the dentist and they assumed he was using an electric toothbrush :)
I’ve always hated the waste of regular toothbrushes and I’m so glad to have a cost-effective solution that works really well!

Meet the Founders
Simon and Thomas are on a mission to rid the world of disposable toothbrushes, one smile at a time.
Nada features an improved brush head connection design, a sleeker brush head shape and a built-in tongue scraper.
No. Grin brush heads do not fit on Nada handles and vice versa. Whichever handle you own will determine the brush heads you buy.
Yes! We intend to keep selling Grin brush heads for as long as there is demand.
