Abstract
Disclosed herein is a toothbrush. The toothbrush (1) includes a head (2), and a through hole (3) formed vertically through the head. The through hole (3) is formed in one or more portions by a predetermined length at a predetermined portion around a front, back, left or right of the bristle body (5) to prevent the bristle body (5) from being separated from the head (2). The bristle body (5) and the head (2) are connected to each other by one or more connecting portions. This toothbrush enables the bristle body implanted with bristles to freely and flexibly move upwards, downwards, leftwards or rightwards in the through hole of the head, so that the bristle body flexibly moves so as to adapt to various shapes of the teeth when brushing the teeth, thereby maximizing the contact area between the teeth and the bristles as well as the brushing effect.
