I switched from a plastic toothbrush and toothpaste in a tube to a bamboo toothbrush and toothpaste tablets that come in a tin can (like Altoid mints). For me, I was looking to get started on participating in the Ecochallenge, but couldn't settle on how to start. When I read an article about bamboo toothbrushes being more eco-friendly, I decided to give it a try. To further my efforts, I included switching out my tubed toothpaste with tablets. Overall, I feel great about my decision. Honestly, I did not think the tablets would have been as effective as regular toothpaste, but it turned out that it was just as good; plus, it was more measurable than regular toothpaste (I know how many brushes I can do until I need to buy some more).
There's a comparative study that measures the effectiveness between regular toothbrushes, bamboo toothbrushes, and neem toothbrushes. The results yielded that bamboo was just as good, and in some cases, better than regular toothbrushes at plaque removal (Ranwa, S., et. al., 2025). The study did indicate that more studies would need to be done to substantiate the results, but knowing that a study was done and the results were in favor of bamboo toothbrushes was encouraging enough. I hope more studies will be done, so that more evidence can be used to inform people to consider switching their toothbrushes.
