The bristles used in bamboo toothbrushes vary from brand to brand. The vast majority of brands use the exact same nylon bristles traditionally used in conventional plastic toothbrushes. At Brush with Bamboo, our bristles are the world’s first to be USDA Certified 100% Biobased. This means that our bristles contain 0% petroleum. Our bristles are made from 100% castor bean oil – a plant-based and renewable resource.
