A dentistry kit for tooth extraction consisting of a vise-type grip member having a joint member engaged by a forked end of a lever whose convexly curved fulcrum surface rests against a planar base plate located on teeth adjacent to the extracted tooth. The connection between the grip member and the lever is thus of the type generally resembling an angularly loose swivel joint. The grip member has two hemispherical tips, for engaging correspondingly shaped indentations drilled in the buccal and lingual side of the tooth. The tool set combines a virtually ultimate simplicity of the elements, resulting in an easy cleaning and disinfection, with an improved operation mainly due to the fact that the extreme pull force can be delicately gauged, while the direction of the force can also be changed by displacing the point of contact between the fulcrum and the base plate.
