A toothbrush (1,3,4,5,6,7) comprising a head portion (11,31,41,51,61,71) having bristles (111) thereon, a neck portion (12,32,42,52,62,72), and a handle (13,33,43,53,63,73) is disclosed. One end of the neck portion is connected to the head portion, and the other end is connected to the handle. The axis of the bristles (111) is substantially parallel to the axis of the neck portion (L1). The axis of the neck portion (L1) and the axis of the handle (L2) form an angle (¸1). Accordingly, the toothbrush can be used easily for brushing and it reduces angle limitations when cleaning the inner surface of the teeth. |
