Is Bamboo Really Eco-Friendly?
When choosing a toothbrush material, consider how bamboo differs from plastic and wood. Bamboo plants grow quickly, need little care and may thrive without fertilizer or pesticides.
When used in its raw form, such as in the shape of a toothbrush handle, bamboo does have a considerably smaller ecological footprint compared to plastic. This is because bamboo is biodegradable. You can compost the handles of bamboo toothbrushes if you first remove the nylon bristles. You can also find ways to creatively reuse the toothbrush handles, such as turning them into plant markers for your garden. However, if bamboo toothbrushes end up in the trash, they aren't significantly more environmentally friendly than their plastic cousins.
If you want a fully biodegradable toothbrush, choose one with a bamboo handle and bristles made from boar hair. Keep in mind that boar hair bristles tend to be rougher than nylon ones, and hard bristles can cause wear on your enamel and contribute toreceding gums.
