Every morning and night, we reach for our toothbrush without much thought. But what if this simple daily habit is quietly contributing to one of the planet’s biggest plastic waste problems? The truth is, billions of plastic toothbrushes end up in landfills and oceans every single year, and most will outlive us by centuries.
The good news: consumers now have choices. By rethinking what we brush with, we can reduce waste, minimize our environmental footprint, and even improve our oral care routines. In this guide, we’ll explore how to make toothbrushes more sustainable, what materials work best, and how companies like Nada Toothbrush are changing the way we clean our teeth—without trashing the planet.
The Plastic Toothbrush Problem
The modern plastic toothbrush was invented in 1938. Since then, nearly every toothbrush ever made still exists somewhere on Earth—either buried in landfills, floating in our oceans, or breaking down into harmful microplastics.
-
Over 23 billion toothbrushes are thrown away each year worldwide.
-
In the U.S. alone, more than 1 billion end up in landfills annually.
-
Each disposable toothbrush takes 500+ years to decompose.
That means a toothbrush you used in childhood could still be intact long after your lifetime. It’s a sobering thought, but also a reminder that the small things add up—and that’s exactly where change can happen.
Strategies for Making Toothbrushes More Sustainable
If you’re ready to reduce waste in your bathroom, here are the key ways to make toothbrushes more eco-friendly:
1. Choose Reusable Handles Over Disposable Ones
The biggest sustainability win comes from keeping the handle and only replacing the head. Most people throw away a perfectly functional handle every 3–4 months just because the bristles wear out.
This is where Nada Toothbrush stands out. Its aluminum handle is designed to last for life. Instead of tossing the whole brush, you simply swap the head and send it back to be commercially recycled. This single change has stopped over 300,000 disposables from ending up in landfills and oceans.
Pro tip: Look for brands that use durable, recyclable materials (like aluminum or stainless steel) for handles instead of plastic.
2. Recycle Brush Heads Responsibly
Even the most sustainable toothbrushes need bristles—and bristles are usually made of nylon, which doesn’t break down naturally. That’s why proper recycling is essential.
Nada designed its brush heads to be commercially recyclable, meaning used heads can be returned and processed responsibly. Instead of assuming “biodegradable” claims will solve the problem (they rarely do), Nada takes accountability for the end of life of each product.
If you use another brand, check whether they offer a take-back program. TerraCycle, for example, partners with some oral care companies to recycle used products.
3. Skip the “Greenwashed” Options
It’s tempting to reach for bamboo toothbrushes because they look eco-friendly. While bamboo handles are compostable, the nylon bristles are not—so most bamboo brushes end up in the same landfill pile as their plastic counterparts.
As Nada’s founder Simon Cooper discovered during product testing:
“We experimented with bamboo, but ultimately it wasn’t the best solution. The bristles don’t decompose, and we didn’t want to give people a false sense of sustainability.”
Sometimes, the “natural” choice isn’t actually the most sustainable. A long-lasting handle + recyclable heads is a smarter approach.
4. Support Circular Design
The future of sustainable products lies in circular design—products that are built to be reused, repaired, or recycled rather than discarded.
Nada Toothbrush was born from this mindset. Simon Cooper’s “aha” moment came one night while brushing his teeth:
“I noticed my toothbrush was worn out; the bristles were frayed and the handle was covered in old toothpaste. A thought occurred to me: why do we throw away the handle? The brush head obviously needed replacing, but a metal handle would be cleaner and last forever.”
From that idea, Simon partnered with an industrial designer to prototype a toothbrush that could truly last a lifetime. The result: a sleek, hygienic aluminum handle paired with recyclable brush heads.
By supporting brands that commit to circularity, you’re not just buying a product—you’re investing in a system that values sustainability from start to finish.
5. Extend the Life of Your Toothbrush
Even with a sustainable design, how you care for your toothbrush matters. Here are simple tips:
-
Rinse thoroughly after each use to prevent bacteria buildup.
-
Air dry upright instead of leaving it in a damp cup.
-
Replace heads on schedule (every 3–4 months, or sooner if bristles fray).
By caring for your toothbrush properly, you’ll ensure the handle truly lasts for life.
6. Advocate for Industry Change
Individual action is powerful, but the real shift happens when industries change. Supporting innovative companies like Nada signals demand for better solutions.
You can also:
-
Ask your dentist if they recommend sustainable options.
-
Encourage oral-care companies to launch recycling programs.
-
Share your switch on social media to inspire friends and family.
Why Nada Toothbrush Is Different
Most “eco-friendly” toothbrushes still create waste. Nada solved this by designing around three principles:
-
Durability: An aluminum handle that lasts forever.
-
Waste Reduction: Replacement heads use ~80% less plastic than disposables.
-
Accountability: Used heads can be returned and commercially recycled.
Simon’s mission wasn’t just to reduce plastic—it was to design a brush that actually performs better. The aluminum handle is more hygienic (easy to clean, doesn’t trap bacteria like plastic), and the heads are engineered for an effective clean.
As Simon puts it:
“We’re thrilled with how much plastic waste we’ve managed to divert from landfill—but we’re not done yet. We’re constantly looking at new materials or design methods to lessen our impact.”
By choosing Nada, consumers aren’t just reducing waste—they’re joining a movement for smarter, cleaner oral care.
Additional Sustainable Oral Care Swaps
While toothbrushes are a major source of waste, they’re not the only one. To create a truly eco-friendly bathroom routine, consider:
-
Toothpaste tablets instead of tubes (which are difficult / impossible to recycle).
-
Compostable floss picks or refillable floss dispensers.
-
Mouthwash tablets or concentrates to reduce plastic bottles.
When combined with a toothbrush like Nada, these small switches make a big impact over time.
Why Sustainability Matters in Oral Care
Some may wonder—does one toothbrush really matter? The answer is yes. Because when multiplied by billions of people, small choices create massive results.
If every household in North America switched to reusable handles tomorrow, we’d keep billions of plastic handles out of landfills within just a few years. That’s the power of consumer action.
And as more people choose sustainable alternatives, companies will follow. Oral care may seem like a tiny piece of the climate puzzle, but it’s one of the simplest areas where we can all make a difference.
