Every toothbrush you've ever used is still on this planet, unless it's bamboo! You can now brush responsibly with a bamboo charcoal toothbrush. Why Are Bamboo Toothbrushes Better? Bamboo handles are naturally antibacterial, antimicrobial and odor resistant, making them ideal for your dental routine. Bamboo, a natural fiber, is biodegradable, unlike its popular plastic alternative. What are the bristles made of? Many bamboo toothbrushes on the market are still not 100% plastic free since their bristles are a type of plastic. However, ours are completely compostable. We've scoured to bring you two options: Plant-based bristles: 100% compostable bristles made from castor bean oil and a sustainably sourced bamboo handle, this toothbrush is gentle on little teeth and the planet. Boar har bristles: Made from natural bristles and a waxed beechwood handle. Dispose of it in your wood-burning stove or compost when you're done with it. Whichever you choose, you can't go wrong with these zero-waste options. We love both of these brushes!
