Researchers have examined the sustainability of different models of the most commonly used oral health product – the toothbrush – to determine which is best for the planet and associated human health.

Although the toothbrush is a widely recommended healthcare device worldwide, there is currently little quantitative data available for its impact on the planet. The research study, in collaboration with Eastman Dental Institute at University College London, is published in the British Dental Journal. It represents the first time a life-cycle assessment (LCA) has been used to measure environmental consequences of a healthcare product.
Healthcare is a major emitter of environmental pollutants that adversely affect health, but awareness of these effects remains low both in the industry and in the general consumer population. There is currently little evidence or guidance regarding the sustainability of specific healthcare interventions, services or devices.
Researchers considered different manufacturing models of the toothbrush and measured the environmental impact (carbon footprint) and human health impact (DALYS) of the toothbrush. The electric toothbrush, the standard plastic brush, the plastic brush with replaceable head, and the bamboo brush were used. The team found that the electric toothbrush was comparatively harmful for planetary health.
