TreeBird's natural bamboo toothbrush with extra soft BPA-free nylon bristles gives you a gentle brushing experience while still getting your teeth squeaky clean. It's the best option for people with sensitive teeth or gums. The handle is made from organic bamboo that's antibacterial - making it the perfect material for a toothbrush! Once you've used it for 2-3 months and are about to swap it for a new one you can easily compost it in your compost pile (remember to pick out the bristles first though). The bristles are Pure White - just as pure as your conscience since you're not creating unnecessary plastic pollution that litters the earth for hundreds of years. Yay!
