A hygienic magnetic eruptor compelling and guiding the eruption of an impacted tooth fully embedded inside the jaw, through the gum and into a dental arch space. An intra-magnetic unit may be bonded to the tip of the impacted tooth inside the jaw bone or placed in the bony plate layer between the impacted tooth and the dental arch space. An intra-oral magnetic unit generating a greater magnetic force than the intra-bony magnetic unit is positioned in the dental arch space for pulling the impacted tooth toward the dental arch space. Initially, a surgical procedure is undertaken to provide a flap in the gum at the desired point of entry for accessing the impacted tooth, and thereafter some of the bone which interferes with the normal eruption of the impacted tooth is removed to provide a tunnel to the tip of the crown of the impacted tooth or to the bony plate adjacent to the impacted tooth. A sterile intra-bony magnetic unit is inserted in the tunnel and secured in place and then the flap is reconnected to the gum for asceptically isolating the sterile intra-bony magnetic unit from the non-sterile oral cavity, to almost simulate the natural eruption process of an impacted tooth.
