The bristles of this classic toothbrush are infused with binchotan charcoal, a fine Japanese activated charcoal that naturally absorbs and neutralizes bacteria from teeth for a deep, natural clean. Binchotan charcoal helps to deodorize your mouth and keeps teeth looking fresh, while also preventing bacterial build up between brushings. This style features sturdy bristles for a deep clean that removes plaque and stimulates the gums. With powerful binchotan infused right in the bristles, the Morihata Binchotan Charcoal Toothbrush is a great alternative to messy powdered charcoal toothpaste. Set includes one yellow toothbrush and one blue toothbrush.
