![]() ![]() In fact, the tool’s tip moves so quickly that it must be cooled by a constant stream of liquid, a process called lavage.īesides keeping the tip from overheating, lavage constantly flushes debris away from the area under treatment. The ultrasonic scaler can rapidly remove tough stains and tartar, meaning less time for the patient in the chair, and less fatigue for the clinician. Some tips are so fine that they can be used not only on the crown surfaces of teeth, but on the roots as well. With its vigorous, repetitive motion, the tip is easily able to break up hardened deposits on the tooth without damaging it. The vibrations are so fast for both types - about 25,000 to 45,000 times per second - that they fall into the ultrasonic range. However, each has a different type of motion: The magnetostrictive variety moves in an elliptical motion, while the piezoelectric variety moves in a linear motion. There are currently two main types of ultrasonic scalers (the piezoelectric and magnetostrictive varieties), but both work the same way - electromagnetic forces coursing through the hand-held unit cause its tiny tip to vibrate rapidly. ![]() Since the removal of plaque and calculus helps eliminate harmful bacteria beneath the gum line, cleaning with an ultrasonic scaler (sometimes called “root debridement”) is a primary means for preventing gum disease. ![]() Why? Because they’re so good at removing the buildup of stains, dental plaque and calculus (also called tartar) from the crown (above the gum) and root (below the gum) surfaces of the teeth. They are the tools of choice for many dentists and dental hygienists. In experienced hands, these high-tech instruments can disrupt and flush away bacteria along with hard deposits that your toothbrush can’t touch - and they can even help moderately stained teeth look brighter.Ĭhances are you may already be familiar with ultrasonic scalers - or at least, your teeth are. Ultrasonic equipment was first used in dentistry back in the 1950s today, ultrasonic scaling is a mature and time-tested technology. When it comes to cleaning your teeth, few dental instruments can match the power and speed of an ultrasonic scaler. ![]()
