ABSTRACT OF THE DISCLOSURE An apparatus and method for cleaning surfaces and crevices of teeth wherein a plurality of tufts of filaments are each rotated in a controlled reciprocating fashion. Furthermore, immediately adjacent tufts are contrarotated. Each tuft is rotated about its own central axis, and placed in contact with the teeth whereby the filaments develop a twisting action dynamically and serially progressing from the base of each tuft to the opposite free ends of the filaments. The plurality of tufts are positioned in two parallel rows, each of which has adjacent tufts staggered with respect to each other.
