ABSTRACT:
A toothbrush for improved execution of the modified Bass method of cleaning teeth comprises a handle having a bristle mounting and disposed at a negative angle relative to the principal axis of the handle. In a specific example, a substantially rectangular array of bristle tufts is mounted on the angled end of the handle, the bristle tufts comprising four columns forming eight rows, the columns being substantially equally spaced at the base and the rows being substantially equally spaced. A forward edge grouping of bristle tufts is provided comprising a row of three bristle tufts. The tufts have from 20 to 150 bristles and the bristles are from 5/16" to 9/16" in length. The two outer columns of bristle tufts are angled inwardly at 7.degree. from the vertical and the two center columns of tufts are angled inwardly at 6.degree. from the vertical, to provide greater firmness against the teeth when the handle is rotated than when the handle is reciprocated along the teeth. The two outer bristle tufts of the row of bristle tufts in the forward edge grouping can be angled inwardly at an angle of 6.degree. to 7.degree. from the vertical, the center bristle tuft being substantially vertical.
