The invention relates to a wax dispenser for dental technology comprising: a wax reservoir in the shape of a hollow tube which contains a liquid wax therein; a nozzle which is disposed on the front end of the wax reservoir and which is in fluid communication with the wax reservoir; a heater which heats wax to keep wax contained in the wax reservoir in liquid state; an air-pressure supplier which increases the pressure in the wax reservoir by the introduction of air from the outside in a pressurization mode and decreases the pressure in the wax reservoir by the discharge of air to the outside in a depressurization mode; and a dispenser actuator comprising a wax passage which allows the wax reservoir to be in fluid communication with the nozzle, and a passage open/shut device arranged to open and shut the wax passage to discharge wax contained in the wax reservoir through the nozzle in the pressurization mode and to introduce wax from the outside to the wax reservoir through the nozzle in the depressurization mode. Therefore, it is possible to facilitate user's convenience and the work efficiency by charging wax in the wax dispenser in the shape of a pen, by discharging wax according to air pressure and by controlling the discharge of wax precisely.
