An apparatus and method for heating an endodontic instrument by infrared radiation includes a housing defining a chamber. An infrared heating element is positioned within the chamber. The housing includes an aperture and an adjacent holder for holding the endodontic instrument, such as an obturator. The endodontic instrument held by the holder extends through the aperture and into the chamber. The infrared heating element directs infrared radiation toward the endodontic instrument, which heats the endodontic instrument.
