Like Magic

Incredibly convenient. Impossibly clean. Zero plastic waste.

Over 3 billion disposable toothbrushes are thrown out every year. So we made Nada — the sustainable toothbrush people love.

Made for life, not landfill

Ditch the disposable. Switch to Nada—an aluminum handle you keep, and toothbrush heads we recycle.

Clean teeth start with a clean toothbrush

Nada rinses clean, lays flat and won’t roll over. Hello clean teeth, so long bathroom yuckies.

Less shopping, more smiling

Cross toothbrush off your list—forever. We deliver fresh brush heads every year and remind you to replace them every 3 months.

Save money and the planet

Starting at just $3 per brush head with free shipping, Nada costs less for you (and mother earth).

Dentist Approved

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. Richard Rapoport, Dental Surgeon, MAGD

Amazing toothbrush! I love the feel of the bristles and the design of the handle. I definitely recommend this product!”

Dr. Paul Sirek DDS

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.”

Melissa, 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!”

Kristen, Registered Dental Hygienist

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.”

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.
