The Last Toothbrush You'll Ever Buy.
One aluminum handle, built to last a lifetime — then you only ever replace the head.
- An aluminum handle that lasts for life
- Floss-tipped bristles for a 6× deeper clean
- Swap the head, not the whole brush
Billions of toothbrushes get tossed every single year.
Every one of them is plastic. And plastic doesn't break down — it sits in a landfill for centuries, breaking into smaller and smaller pieces that seep into the soil and water.
The toothbrush you used this morning will still be here long after you are.
It's the last piece of plastic in your bathroom no one's been able to replace — until now.
The handle lasts a lifetime — you just replace the head.
One handle, made from solid aluminum — keep it for life, not 3 months. After that, you only ever replace the head.
Pop the old head off, drop it in the pre-addressed envelope (add a stamp), and we recycle it. Pop a fresh one on. The only thing you ever throw away is a head the size of your thumbnail.
Independent science ranked this design the most sustainable.
The first peer-reviewed study to weigh every kind of toothbrush across 16 environmental impacts — carbon, water, waste. The replaceable-head design won.
The takeaway: Nada is built on the design that came in first — a handle you keep, a head you replace.
The study (Lyne et al., British Dental Journal, 2020) tested replaceable-head bamboo/bio-plastic brushes, not Nada — it proves the design wins, not the brand. We just built the best version of it.
Nada cleans 6× deeper.
A better clean comes down to the bristles. Most are flat and blunt — they skate over the surface and miss the two spots that matter: just below the gumline, and the tight gaps between your teeth. That's exactly where plaque builds up.
Nada's bristles are floss-tipped — up to 17× thinner at the tip. They slip into those gaps and sweep out what a flat brush leaves behind. That's the 6× deeper clean. It's why it feels like you just left the dentist.
"I've tried soft brushes for two years, even an expensive electric. None of them cleaned in between my teeth as well as this."
One brush, for good — and nothing left in a landfill.
The aluminum handle is covered by a lifetime warranty. No more tossing the whole brush every few months — you only replace the brush head. You buy it once, and you're done thinking about it.
You've also closed the loop for good. The handle is infinitely recyclable, and the used heads go to TerraCycle to be made into new products.
Not a sacrifice. An upgrade you'll be glad you made.
Great for the planet. Great for your wallet.
Buy the handle once. After that, the only thing you pay for is the cheap part — the head. Here's what it actually costs:
- A typical disposable: about $7 a brush, swapped every 3 months like dentists recommend — roughly $28 a year, every year, forever.
- Nada: $25 for a handle and three brush heads to start. After that, $20 a year for heads — or $15 a year when you subscribe.
So price isn't the catch. Over the years, Nada costs about what you'd spend on disposables anyway — even a bit less if you subscribe. The real win: you keep the handle for life, and toss a fraction of the plastic.
