They’re cheap. Ubiquitous. Easy to toss.

But disposable toothbrushes are quietly fueling one of the most overlooked waste problems in personal care—and the real cost goes far beyond the checkout line.

In this post, we’re looking past the price tag and diving into the hidden environmental impact of plastic toothbrushes. Because if sustainability matters to you, it’s time to rethink what you brush with.

One Billion Toothbrushes: Where Do They Go?

The American Dental Association recommends replacing your toothbrush every 3–4 months. That means most people go through four toothbrushes a year.

Multiply that by the global population, and we’re looking at billions of plastic toothbrushes tossed annually—none of which are curbside recyclable.

According to National Geographic, plastic toothbrushes are among the top contributors to plastic pollution because they’re:

• Too small for recycling machinery
  

• Made from mixed plastics that can’t be separated easily
  

• Not designed with end-of-life in mind
  

They end up in landfills, oceans, and ecosystems—where they can stick around for hundreds of years.

Why “Recyclable” Isn’t the Whole Story

Some companies claim their toothbrushes or bristles are recyclable—but the reality is murky. Unless you’re part of a closed-loop system (like Nada’s), the odds of your toothbrush actually getting recycled are slim.

Without a dedicated program and infrastructure, most recyclables are either downcycled or rejected entirely. They’re just not built into the system.

That’s why at Nada, we created a closed-loop recycling program that ensures your used brush heads don’t become waste. You send them back—we recycle them responsibly

The Problem with Throwaway Design

Disposable toothbrushes are built to be replaced. Which means:

• Durability doesn’t matter
  

• Materials are chosen for cost, not impact
  

• Waste is baked into the business model
  

But what if the brush you used every day was designed to last a lifetime?

That’s the idea behind Nada’s aluminum handle: a one-time purchase that replaces a lifetime of plastic. The only thing you’ll ever replace is the brush head—and even that gets returned to us to be recycled properly.

Made Here. Not Shipped Around the World.

Most toothbrushes are mass-produced overseas and shipped across the world, adding tons of hidden emissions through global supply chains.

Nada is proudly made in Canada. Local production means:

• Lower transportation emissions
  

• Safer labor standards
  

• More transparency around how and where your products are made
  

It’s not just about what goes in your mouth—it’s about the values that go into your brush.

From Disposable to Intentional

Every toothbrush you’ve ever used still exists somewhere on this planet. That’s a sobering thought—but also a motivating one.

We can’t undo the past, but we can choose better moving forward. Choosing a system that’s designed for sustainability from the start—like Nada—is a small switch with long-term impact.

The Bottom Line

Disposable toothbrushes:

• Aren’t actually recyclable
  

• Aren’t built to last
  

• Aren’t aligned with a sustainable future
  

Nada is.

We believe in thoughtful design, real recycling, and products that don’t pretend to be eco-friendly—they actually are.
