PURPOSE: A replaceable interdental brush is provided to facilitate the mounting of the interdental brush and to minimize the replacement costs of the interdental brush. CONSTITUTION: A replaceable interdental brush comprises an interdental brush wire(60), a handle unit(120), an ultrasonic wave oscillation module(220), an ultrasonic wave transfer module, a drive circuit(320), an elastic metal body(300), and an acoustic impedance(200). The ultrasonic wave oscillation module generates ultrasonic waves in the brush of the interdental brush. The ultrasonic wave transfer module transfers ultrasonic wave to the interdental brush. The drive circuit drives the ultrasonic wave oscillation module and ultrasonic wave transfer module. The elastic metal body and acoustic impedance effectively transfer ultrasonic waves to the brush.
