The method of tooth extraction depends mainly on the specific situation of the tooth: i. If it is a stump, the surface of the stump is covered with gums, the surface of the covered gums need to be removed with an electric knife or scalpel, and then the stump can be extracted with extraction forceps and tooth jacks. Second, if it is a complete loose tooth, the tooth can be extracted or jerked out directly using extraction forceps or jaws. Third, in case of multiple teeth, surgical cutting drill can be used to remove the teeth one by one by dividing the crowns and roots, which can reduce the trauma of extraction trauma. IV. For extraction of complex teeth, it may be necessary to cut the gums, flap, expose the alveolar bone, expose the maximum circumference of the crown, perform crown splitting and root splitting, eliminate resistance, and extract the tooth in pieces, which requires suturing and hemostasis after surgery.
