Toothbrush Lifespan This ecological bamboo toothbrush will last just as long as a conventional plastic toothbrush. Please see the details on the Proper Care page. True Sustainability Bamboo is the fastest growing plant on earth. Because it contains naturally-occurring antimicrobial agents, there is no need for using fertilizers or pesticides during its cultivation. Their bamboo is totally organic and wild. After they harvest a bamboo stalk to use it for toothbrushes, another stalk takes its place and grows to full size within just 2 years — a remarkable growth rate!
