An endodontic obturator (10) for obturating a root canal includes a wire (18) made of a conductive material, a carrier (12), and a sheath (14). The carrier (12) is configured to releasably couple to the wire (18) and is made of a first thermoset material. The sheath (14) is configured to slidably receive the carrier (12) and is made of a second thermoset material. The melting temperature of the second thermoset material is lower than the melting temperature of the first thermoset material. A method of making an endodontic obturator comprising molding a carrier (12) made of a first thermoset material around a conductive wire (12), molding a sheath (14) made of a second thermoset material, and coupling the carrier (12) and the sheath (14).
