Disclosed herein is a dental compound gun. A body unit has a gun shape. A compound material stick is inserted into the body unit through an insert hole formed in the body unit. A feeding unit transfers the compound material stick to an outlet. A melting unit heats the compound material stick and discharges melted compound material out of the body unit. A drive unit includes a trigger and a motor. A control unit controls power to be supplied to the motor. A support unit is coupled to a lower end of the body unit so that the body unit can be placed upright on a support surface. The control unit controls the motor in such a way that when the operation signal of the trigger is generated, the motor is forwardly rotated, and when the operation signal of the trigger is interrupted, the motor is reversely rotated.
