Abstract

A toothbrush for use by wearers of orthodontic appliances comprises an elongated handle, a neck and a head. The bristles are designed so that the outermost rows are relatively soft and of long length, the bristles in the pattern gradually shortening in length and becoming stiffer, with the shortest and stiffest bristles being positioned along the center rows of the brush's longitudinal centerline axis. Also, the center rows of bristles are formed to be angled at their ends to reduce the pressure required to deflect the bristles beneath brace elements thus reducing undue pressure against the gums. Furthermore, a flexible member compressibly supports the center rows of bristles.
The toothbrush also comprises an outer bumper protectively surrounding the toothbrush head. Moreover, a further embodiment of the invention has a lower tuft of bristles projecting from the lower portion of the handle.
