PROBLEM TO BE SOLVED: To provide an edible toothbrush to solve the issues that a parent brushes teeth of a child who cannot brush teeth by him-/her-self, a tooth brushing helper brushes teeth of a bedridden patient; and tooth brushing is not easy in a vehicle or a place without water upon an emergency disaster. SOLUTION: A whole body of this toothbrush is formed of an edible material. Bristles are planted in over 40% of the whole area of the toothbrush to solve the issues. COPYRIGHT: (C)2006,JPO&NCIPI
