The plaque on the back of this back tooth was not removed because the tip did not sufficiently reach behind the back tooth. Even the gingival pockets have no hair tips. The improved toothbrush (Fig. 4) has short hairs and a length of about 2cm, and the length of the flocked teeth is about 2cm. The effect of the lower teeth is greater than that of the conventional toothbrush (Fig. 3). As the effect on the back shows in the use state diagram of FIG.
Because the bristles do not reach the back of the back teeth sufficiently, the plaque in this area cannot be removed, much less the gingival pocket. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems As shown in FIGS. 1 and 2, a flocking portion (1) in which the area of the flocking portion is reduced as much as possible.
First, elastic hair (2) having a length enough to reach the gingival pocket on the back of the back teeth is implanted in such a manner that the amount of the bristles falls into the back of the back teeth. The present invention is a toothbrush for back lining of a back tooth configured as described above.

[0005]

Embodiments of the present invention will be described below. As shown in FIG. 1 and FIG. 2, elastic hair (2) having a length sufficiently reaching the gingival pocket on the back of the back tooth is placed on the back part (1) where the area of the back part is reduced as much as possible.
