Bamboo vs Plastic Toothbrush
Bamboo wins — the handle returns to soil while a plastic stick persists for centuries.
Dentists recommend replacing your toothbrush every three months. Over a lifetime, that's roughly 300 brushes per person. The handle material decides where they end up.

The differences
| Bamboo | Plastic | |
|---|---|---|
| Handle material | MOSO bamboo | Polypropylene |
| Bristles | Nylon (removable) | Nylon (bonded) |
| Compostable handle | Yes — 6 months hot compost | No — never |
| Plastic per brush | ~1g (bristles only) | ~17g |
| Brushes per lifetime | 300 | 300 |
Why one wins
A standard plastic toothbrush is a moulded polypropylene stick that no recycling facility will accept — too small to sort, too multi-material to process. Every brush you've ever owned is, in some form, still on the planet.
A bamboo handle is grown in 3-5 years, harvested without replanting, and decomposes back into soil in 6 months in a hot compost. Only the nylon bristles need to be pulled out at end-of-life.
Cleaning performance is identical when the bristle profile (DuPont nylon, soft, rounded) is the same. The choice is purely about what the handle does after you throw it away.
