Abstract: A toothbrush with silicon rubber bristles is disclosed. The bristles are soft and have both a high polishing power and a high water repellency, thus effectively cleaning teeth without injuring one's teeth or gums. The toothbrush consists of a long handle with a longitudinal opening at one end. A brushing head with the silicon rubber bristles is attached to the opening of the handle. The bristles easily remove foreign substances such as food remnants from teeth or gums and effectively brush the inside, outside and top surfaces of each tooth simultaneously, thus saving time while brushing teeth. The bristles include a plurality of finely rugged bristles.
