The soft and smooth texture of bamboo bristles makes them gentle on gums, reducing the risk of irritation and damage to delicate oral tissues. Unlike some plastic toothbrushes with harsh bristles, bamboo toothbrushes provide a comfortable brushing experience without causing abrasions or discomfort. Bamboo is a bio-degradable material. So, once you think it's time to replace your bamboo toothbrush, you can cut it into small pieces and compost it.
