The very thin toothpick is fitted at one of its ends with a hook which allows interdental cleaning carried out from the inside outwards. Its body comprises a groove which contains a "tensor" or "nerve" which is used to modify the strength and rigidity of the assembly by simple lateral pressure. It consists of: (1) - body of the toothpick (2) - end in the form of a fine and flattened point (3) - "nerve" (4) - highly pointed hook perpendicular to the axis of the toothpick, useful for removing food debris at the base of the dental crowns and in the interdental spaces from the inside outwards (5) - second end of the toothpick This article is manufactured according to the techniques of mechanical cutting or moulding. <IMAGE>
