Abstract
An interdental toothbrush includes one or more wires having fixed filaments disposed on the wires, 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 and guiding the wires and the filaments to engage into the predetermined or suitable or 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 thus for preventing the user's gum from being hurt or injured by the greater filaments.
