Denture brusher

A denture brusher, comprising:

• a denture brush;
• a holder whose surface on a side opposite to a bottom of the holder is open and in which a bottomed denture-brush-housing portion that is capable of housing the denture brush is formed;
• a motor that drives the denture brush by an on-off operation of a switch;
• a detection means for detecting whether a denture that is a to-be-brushed part is set in the denture brush,
• wherein the denture-brush-housing portion includes a bottom,
• wherein, when the detection means detects that the denture has been set in the denture brush, the switch is turned on and the motor is driven,
• wherein, when the detection means detects that the denture is not set in the denture brush, the switch is turned off and the motor stops being driven, and
• wherein the denture brush includes:
• a frame composed of a flat plate-shaped base and a plurality of wall pieces disposed at an outer circumferential part of the base;
• first bristle tufts arrayed on the wall pieces;
• second bristle tufts arrayed in a center region of the base;
• and
• third bristle tufts arrayed on an outer circumferential side of the second bristle tufts and that has an openable/closable structure in which switching is performed between an open state in which the wall pieces are positioned radially along the outer circumferential part of the base so as to be horizontal with respect to the base and a closed state in which the wall pieces are positioned so as to stand upright with respect to the base.
