An apparatus (40) and method for applying gutta-percha (42) to a shank-like carrier (22) with which the gutta-percha is in- troduced into an extirpated root canal utilizes an elongated hollow barrel (44) for holding an amount of gutta-percha and a plunger (46) fitted within the barrel for sliding movement along the length of the barrel. The barrel is provided with a discharge opening (56) at one end thereof into which one end of the shank-like carrier may be inserted. Upon heating the gutta-percha con- tained within the apparatus to a softened condition, inserting one end of the shank-like carrier through the discharge opening, and then urging the plunger toward the discharge end of the barrel to dispense gutta-percha therefrom while withdrawing the car- rier from the discharge opening, the surface of the carrier is coated with the gutta-percha.
