The Toothbrush You Throw Away Every 3 Months Is a Bigger Problem Than You Think
How much plastic toothbrush waste gets generated every year, why bamboo is better, and how to compost the handle when you are done.
You replace your toothbrush every three months. Your dentist says to. Four times a year, every year, for the rest of your life. That is a small and ordinary thing. It is also, multiplied by 8 billion people, one of the most persistent plastic waste problems on the planet. Here is what is actually happening, why bamboo changes the equation, and exactly what to look for before you buy.
Halloween + Oral Care
You Are Going to Need to Brush After That Candy.
Halloween is the single highest candy consumption night of the year. The average child collects between 3,500 and 7,000 calories worth of candy in a single trick-or-treat session. Adults are not far behind. All of that sugar sits on teeth, feeds bacteria, and produces the acid that causes cavities. Your dentist is already bracing for November.
Which means Halloween is actually one of the most important toothbrush moments of the year. You are going to brush that night and probably twice the next day. If you have been meaning to swap your plastic toothbrush for a bamboo one, there is no better time to do it than before the most sugar-intensive night of the calendar.
Americans spend around $3 billion on Halloween candy every year. Most of it is individually wrapped in multi-layer plastic and foil that cannot be recycled. The candy generates waste before it even hits your teeth.
A bamboo toothbrush brushes off the sugar exactly the same way a plastic one does, but with less waste. It's all a matter of choice: one that ends up in a landfill for 400 years when you are done with it in January or one made from bamboo that will return to the earth instead.
The holidays are coming. So is a lot of treats, a lot of sugar, and a lot of brushing. Do it with something thats kinder to the earth when you are done.
The Numbers
How Bad Is the Plastic Toothbrush Problem?
Four billion plastic toothbrushes are thrown away every year around the world. One billion of those come from the United States alone, generating roughly 50 million pounds of plastic waste annually. Every single one of those toothbrushes will still be on this planet in 400 or more years. The first plastic toothbrush ever made is still out there somewhere.
The scale is hard to visualize. So here is another way to think about it: if you brush your teeth twice a day from age 3 to age 80, you will personally throw away around 300 plastic toothbrushes in your lifetime. None of them will go away.
Why Plastic Toothbrushes Are So Difficult to Deal With
- Most toothbrushes are made from a combination of polypropylene plastic, nylon, and rubber, three different materials bonded together in a way that makes them almost impossible to separate for recycling.
- They cannot go in standard curbside recycling. The mixed materials contaminate the recycling stream.
- Specialized recycling programs exist through a small number of companies, but they require the consumer to mail the brushes in and are not available in most cities.
- The nylon bristles, even on most bamboo toothbrushes, are not currently biodegradable at a commercial scale. This is the one part of the toothbrush problem that has not been fully solved yet.
- Most toothbrushes end up in landfill, where they persist for four centuries. A significant number also end up in the ocean, where they photograph well in plastic pollution campaigns because they are instantly recognizable.
"Every toothbrush you have ever used still exists somewhere, unless it's bamboo."
The Better Option
Why Bamboo Is Actually Better
Bamboo is one of the fastest-growing plants on earth. Some species grow up to three feet per day. It requires no pesticides, almost no water beyond natural rainfall, and regenerates from its own root system after harvesting without needing to be replanted. It sequesters carbon as it grows. And it also composts at the end of its life.
Most of a conventional toothbrush, by both weight and volume, is a polypropylene plastic handle. Ours replace that handle with bamboo. The bristles are made from castor oil and charcoal, and our kids’ toothbrushes use bristles derived from castor oil, so none of them rely on petroleum based plastic. When your brush reaches the end of its life, remove the bristles and dispose of them separately, then compost the bamboo handle. The part that makes up the bulk of the toothbrush goes back into the earth instead of a landfill.
What Bamboo Actually Offers
- The handle is made from sustainably harvested bamboo, a renewable resource that grows back without replanting.
- Bamboo is naturally antimicrobial, which matters for something that lives in your bathroom and gets wet twice a day.
- Bamboo can compost completely, keeping the largest part of the toothbrush out of landfill entirely.
- No petroleum-based materials.
- Ships in plastic-free, kraft paper packaging. No unnecessary plastic wrap.
- Works identically to a conventional toothbrush. Same bristle stiffness recommended by dentists, same ergonomics, same clean.
The honest caveat: the bristles still need to be removed before composting because they are polymerized through a heat process to make them durable enough for daily brushing. Our bristles are made from castor bean oil rather than petroleum, which is a real improvement over conventional nylon, but they will not break down in a home compost pile. Remove them with needle nose pliers, put them in the trash, and the bamboo handle goes into your compost pile. You are still keeping the majority of the brush out of the landfill and petroleum-based plastic out of your mouth.
The Buyer's Guide
What to Look For Before You Buy a Bamboo Toothbrush
Not all bamboo toothbrushes are equal. The category has grown fast and some products use the bamboo handle as a marketing angle while cutting corners on everything else. Here is what actually matters.
Moso bamboo specifically
Moso bamboo is the species used in most quality bamboo toothbrushes. It is not a food source for pandas, grows extremely fast, and produces a dense, durable material that holds up to daily use without warping or splintering when kept dry between uses.
What the bristles are actually made from
Most bamboo toothbrushes use petroleum-based nylon bristles. Ours use bristles made from castor bean oil instead, which is a plant-based alternative that does not draw from fossil fuels. The castor bean oil is polymerized through a heat process so the bristles perform exactly like conventional bristles. They still need to be removed before composting the handle, but the material itself is a meaningful step away from petroleum.
Plastic-free packaging
A bamboo toothbrush shipped in a plastic package and plastic mailer undermines the whole point. Look for recycled cardboard, kraft paper, or compostable packaging. The packaging should generate zero plastic waste, otherwise, what's the point?
The right bristle softness
Our toothbrushes have medium soft bristles, a middle ground that cleans effectively without being harsh on enamel or gums. Dentists generally steer most people toward the softer end of the spectrum, since firmer bristles combined with aggressive brushing can wear down enamel and irritate gum tissue. If you are switching from a conventional brush, medium soft is a comfortable place to land for most people. Let the bristles do the work and use light pressure.
A little extra care for the handle
Bamboo can absorb moisture and degrade faster if it sits in water between uses. A good bamboo toothbrush should be stored upright in a holder that lets air circulate around the handle. Kept dry, a bamboo handle will last the full three months without any issues.
End of Life
How to Compost the Handle Properly
This is the part most people skip, which means the bamboo handle ends up in the trash with the nylon bristles still attached. That defeats the purpose. Here is exactly what to do when it is time to replace your brush.
Our bristles are made from castor bean oil instead of petroleum, which is a meaningful upgrade from conventional nylon. That means they will not break down in a home compost pile the way the bamboo handle will. The bristles need to come out before the handle goes into your compost pile.
Here is the easiest way to do it:

A Note on Compostability Testing
We want to be transparent with you: we are a small, passionate team and formal compostability testing is something we are actively working toward. We want to get it right and have the data to back it up before we make any official claims. In the meantime, bamboo is a well-documented compostable material and the guidance above reflects the best available information on home composting bamboo handles.
To everyone who has reached out to ask about this: thank you. Genuinely. Customers who care enough to ask hard questions about what their products are made of and where they go at end of life are exactly the people we built this brand for. It means everything to us that you hold us to a high standard. We are working to meet it.
"Thirty seconds with a pair of needle nose pliers. That is all it takes to keep the bamboo handle out of the landfill."
