To provide a toothbrush with a lapping head formed so that not only the healthy but also an infant, aged people, or hand-impaired people, to say nothing of the healthy, can surely remove plaque within a short time.

The toothbrush comprises a holding grip 1 to be a holding part, a lapping head 5, which is a brush part attached to a front edge of the grip 1 and shaped to wrap outer circumference parts of teeth to be brushed, provided with implanted bristles on each inner surface. The lapping head 5 is rotatable around an axis line of the grip 1 so as to enable easily brushing even in a state that it is impossible for the grip 1 to maintain a parallel state with a tooth line surface.
