ABSTRACT:
A new and improved toothbrush construction comprising spaced groups of bristles extending from the head of the brush. In an alternative embodiment, the bristle groups are supported on slidable elements which may be adjustably positioned and then locked into place on the toothbrush head thereby permitting the spacing of the bristle groups to be varied in accordance with personal requirements. In yet another embodiment, the individual bristles are provided with longitudinally spaced conical protrusions for facilitating the delivery of a hygienic substance or dentifrice to the teeth.
