ABSTRACT:
A toothbrush holder for training the bristles of a toothbrush into a preferred shape utilizes a pair of opposed cam surfaces to urge a pair of rigid compression members against the sides of the mass of bristles along a line at a predetermined height on the bristles. The resultant bristle structure is maintained by repeated storage of the brush in the holder between use.
