A toothbrush with a brushing head (1) in which are provided a number of bores (6) which pass through the superior face (7) of the block (3) consisting in the brushing head, following an axis (14) orthogonal to the base (2), in which, tufts (9) of bristles (8) housed and bound in capsules (30) in a number equal to that of the bores (6), slide in both up and down directions; the capsules (30) containing the tufts of bristles (9) have at the inferior ending (34) shock diminishing means (42) for each single tuft (9), such as to absorb its deformation compensating for the projection and retraction desirable for the bristles (8), during the action of cleansing the teeth. Said capsules (30) are provided with means (38) which allow rotation in a clockwise direction (16) while sliding downward (16) and in a counterclockwise direction (18) while sliding upward. |
