This brush is a dental designed to clean the mouth without the need of water like a toothbrush. It's used by scraping the tongue with the curved side. The tongue contains a majority of the mouth's bacteria, so the scraping would clean the mouth effectively. The other end of the tool is pointed, to act as a simple toothpick. A wire can be ran through the hole on the brush end for strapping to the hand. It's designed to be disposable, because cleaning with water would be pointless.
