Dentists recommend daily interdental cleaning to clean the 40% of your tooth a toothbrush can't reach, remove plaque, a leading cause of tooth decay, and help fight bad breath. Dentek has gone green with brushes made from a naturally derived, organic, plant-based resin and plant-based bristles. This ensures you get the same great Dentek quality whilst being kinder to the planet. Features a new renewable plant-based bio resin handle & brush, reusable daily, with antibacterial handle & bristles. Vegan, not tested on animals & BPA free.
