CONSTITUTION: A teeth scaler comprises a hand piece(110), a head(130), a body(120), an ultrasonic oscillator(140), a horn(150), and a flux prevention pipe(170). The hand piece is formed into a size which can be gripped by a hand. A display is included on top of the body and displays the operating state. The display includes a power button in the lower part and controls the operation of the ultrasonic oscillator. A penetration hole is formed in the center of leading end in the head. A backend of the horn is penetrated in the center of leading end in the head. The ultrasonic oscillator generates supersonic vibration. The horn additionally amplifies the supersonic vibration one more time which is occurred from the ultrasonic oscillator and practically scales by delivering to the teeth.
