Is Your Toothbrush Sustainable?

Researchers at Trinity College Dublin in collaboration with Eastman Dental Institute at University College London for the first time researched the life-cycle assessment of the toothbrush. Researchers looked into both the environmental impact and human health impact of the toothbrushes.

Four types of toothbrush were reviewed: 

  • Plastic manual: plastic handle with fixed head 
  • Bamboo manual: bamboo handle with fixed head

  • Electric: handle and charging unit, with replaceable heads 

Researchers found the most environmentally sustainable toothbrush is the recycled plastic toothbrush.
