(Tooth) brush up with truth: Electric is the worst, bamboo not great either
Climate change potential of electric toothbrush was 11 times greater than the bamboo toothbrush, the study found
Little thought goes into choosing a toothbrush — it is much lesser when one analyses the impact on the planet or associated human health.
A new research, however, has tried to measure the environmental consequences of the healthcare product: It found that electric toothbrushes were the least environment-friendly when compared to other types, and that bamboo toothbrush was not as healthy as it is usually thought to be.
The study was conducted in collaboration with Eastman Dental Institute at University College London and published in the British Dental Journal.
Researchers studied four types of toothbrush: The electric toothbrush, the standard plastic brush, the plastic brush with replaceable head, and the bamboo brush to measure the environmental impact (carbon footprint) as well as the human health impact of the toothbrush.
The team found that electric toothbrush performed consistently poorly compared to the three manual toothbrush types and had the greatest impact in 15 out of 16 environmental categories.
The climate change potential of the electric toothbrush was 11 times greater than the bamboo toothbrush, the study found.
The bamboo and replaceable-head plastic toothbrushes had the lowest impact in all categories. The bamboo toothbrush was, however, not the most environmentally suitable toothbrush, contrary to popular belief. A plastic manual replaceable head toothbrush was probably the best bet, according to the study.
The study found that using bioplastic instead of polypropylene plastic for the toothbrush handle yielded unfavourable results, as this only ...
