The vibrating tip causes some of the water to break into millions of tiny bubbles, an effect called cavitation. This ruptures the walls of bacterial cells and helps create an environment that’s less hospitable to harmful bacteria.
Ultrasonic Scaling vs. Hand Scaling
Studies show that a thorough ultrasonic cleaning takes about one-third less time as compared to hand scaling — which means you need less time in the chair. Many patients prefer ultrasonics to other types of scaling, possibly because it requires the clinician to use less force than a hand scaler to get the same effect. In ultrasonic scaling, only the tip of the tool touches the tooth surface, and only for a short time.
It’s also possible to remove deposits of plaque and tartar from under the gum line by using an extremely small tip on an ultrasonic unit, which can cause less discomfort and result in a deeper and better cleaning. Sometimes an ultrasonic scaler is used first, and then any stubborn areas are scaled by hand.
The Experience of Ultrasonic Scaling
Anyone who has a substantial buildup of tartar or is prone to gum disease can benefit from ultrasonic scaling. It can also help to remove stains from coffee and cigarettes, for example. Yet, for all its power, most people experience little or no discomfort during the procedure.
If you have very sensitive teeth, it may be possible to alleviate some discomfort by using slimmer tips on the scaler. Alternatively, a topical anesthetic may be applied, or conscious sedation can be administered. The power range, the flow of lavage water and the frequency of tip vibration may also be adjusted for increased comfort.
Special tips are also available to clean composite or porcelain tooth restorations, titanium implants, or areas of demineralization (enamel loss) on your teeth. If you have a cardiac pacemaker, be sure to alert all dental professionals/personnel before ultrasonic scaling treatment, so precautions can be taken.
