An endodontic obturator for filling an endodontically prepared root canal of a tooth. The endodontic obturator includes an elongated shaft of having a proximate portion and a distal portion. The proximate portion has a handle portion connected thereto or is suitable for being releasably connected to a handle portion. A layer of filler material is coated about the shaft. The filler material has a low operating temperature at which it becomes plasticized or partially molten. The filler material in the layer disposed close to the distal end can have a higher viscosity at the operating temperate than the filler material close to the distal end.
