ABSTRACT:
A motorized interdental toothbrush includes one or more wires having fixed filaments, and a gage disposed on one end portion of the wires and having an outer diameter equal to or smaller than that of the filaments for limiting the wires and the filaments to engage into the selected interdental spaces between the teeth of the user and for preventing the filaments from being inserted and engaged into the interdental spaces having a relatively smaller width and for preventing the user's gum from being injured by the greater filaments, and a rotating device may be coupled to rotate and drive the brush device to clean the interdental space.
