What Is an Ultrasonic Scaler?

Ultrasonic scalers are used to effectively remove plaque and stones from the teeth and to remove inflamed tissue from the crevice wall. The ultrasonic scaler features automatic frequency tracking to ensure that it runs at the most efficient frequency for optimum performance.


There are different types of cheap China ultrasonic scaler, but they all work in a similar way: the electromagnetic force in the unit’s hand-held “wand” causes its tiny tip to vibrate quickly. These vibrations occur at a faster rate than the speed of sound, effectively blowing away plaque, tartar and stains from the tooth surface.

Compared to hand scaling, thorough ultrasonic cleaning time is reduced by about a third – which means you need less time in the chair. Many patients prefer ultrasonics to other types of scaling, probably because it requires the clinician to use less force than a hand scaler to achieve the same effect. In ultrasonic scaling, only the tip of the tool touches the tooth surface and only for a short period of time.

By using a very small tip on the ultrasonic device, it is also possible to remove plaque and tartar deposits from under the gum line, which can reduce discomfort and result in deeper and better cleaning. Sometimes use an ultrasonic scaler first, then scale any stubborn areas by hand.

If you have very sensitive teeth, you can relieve some discomfort by using a slimmer tip on the scaler. Alternatively, a topical anesthetic may be applied, or conscious sedation can be administered. It is also possible to adjust the power range, irrigating water flow and tip vibration frequency for increased comfort.
