Abstract: The present invention discloses an induction heating type dental filling device including a body unit grippable by a user, a filling unit containing a refillable filling material and connected to the body unit so that one side thereof is insulated from the body unit, a heating unit disposed in close contact with the filling unit and heating the filling material using induced current to convert the filling material into a liquid state, a pressing unit for pressing the heated filling material to discharge the heated filling material to the outside of the filling unit, and a shielding unit for shielding the heat and magnetic field of the heating unit. According to this configuration, heat loss through the filling unit may be prevented and clamping force for the body unit may be excellent, so that the efficiency of filling a filling material for dental treatment may be improved.
