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.”
We make Nada to last for life. Have a problem? We’re here for you.
You don’t have to pay for shipping because we do. That’s love.
Don’t love your toothbrush? We’ll give you a refund within the first 100 days.
