One of the first eco-friendly swaps many aspiring zero wasters make is trading their plastic toothbrush for a bamboo one. But is a bamboo toothbrush really the most sustainable option, or are there any zero-waste toothbrushes with reusable handles? Are there any toothbrushes made from other materials that are more eco-friendly? 

Keep reading to learn more about what makes a toothbrush environmentally-friendly, plus our recommendations of zero-waste toothbrushes that are a bit more innovative than bamboo brushes.

Are bamboo toothbrushes good for the environment?

Bamboo toothbrushes are a solid eco-friendly alternative to plastic toothbrushes. Bamboo toothbrushes can be composted (with the exception of the bristles, in most cases). They are also naturally antimicrobial, and bamboo grows very quickly, making it a generally sustainable crop.

Some of our favorite standard bamboo toothbrushes are made by Brush With Bamboo, Wowe, and Bite. Unfortunately, most bamboo toothbrushes’ bristles are not biodegradable as they contain some plastic – even on the most eco-friendly of toothbrushes. On these, you have to remove the bristles using household pliers before composting the handle.

Note that if you see a bamboo toothbrush claiming to include “natural” bristles, these are typically made from boar bristles, making them compostable, but not vegan (and meaning your purchase supports the meat industry, as these boar bristles are generally byproducts of pigs slaughtered for meat). 

In contrast, no part of plastic toothbrushes are conventionally recyclable. The only somewhat-widespread way to recycle toothbrushes of any brand is via TerraCycle’s oral care recycling program.

So, if you want to move away from environmentally-unfriendly conventional plastic toothbrushes, bamboo toothbrushes are an affordable and popular choice — but there are also a few other zero-waste options on the market.

Etee’s Bamboo Toothbrush With Replaceable Head

Etee’s bamboo toothbrushes feature a reusable bamboo handle that can be reused over and over, or composted if it ever wears out or breaks. The company also offers compostable bamboo replaceable brush heads. You do have to remove and trash the bristles and metal staple before composting the heads, even though the bristles are made from castor bean oil. Etee’s brushes go for $5, and replacement heads are $8 for a pack of two.

The Humble Co.’s Toothbrush With Replaceable Head

Similarly, cruelty-free personal care company The Humble Co. makes bamboo toothbrushes with replaceable heads. However, it appears that you cannot purchase replacements without ordering a handle, too. That said, for €9.99 (around $12 USD) you can get a Humble Co. bamboo handle plus three heads. The bristles are made from nylon, and must be taken out and trashed before composting heads and handles.

Colgate’s Keep

Even major brands are getting in on the low-impact toothbrush trend. In February 2021, the Colgate Keep was unveiled, which features a reusable 100 percent aluminum handle and replaceable plastic brush heads, designed to use 80 percent less plastic than conventional plastic toothbrushes. The brush heads can be recycled through the above-mentioned TerraCycle oral care program, which Colgate actually sponsors.

Unfortunately, Colgate is not a cruelty-free company, and the brushes do contain more plastic than most other options on this list. That said, it’s a great start that Keep toothbrushes and replacement heads will be available at major retailers including Amazon and Target, making them potentially the most accessible option on this list. You can get a Colgate Keep handle with two brush heads for $9.99, or a pack of two heads for $4.99.

Radius also sells replacement heads that are made of vegetable-based nylon, fit into any of the company’s handle designs, and come in different lengths and bristle types. According to Radius, the company’s reusable toothbrushes are 93 less wasteful than the average plastic toothbrush. Radius also makes toothbrushes for children and dogs, though those do not offer replacement heads. Radius’ products are available on the company’s website starting at $3.99, as well as EarthHero.
