Dental cleanings involve plaque removal (soft, sticky, bacteria film) and tartar (calculus) deposits that have built up on the teeth over time. Your teeth souse in saliva continually and the saliva contains calcium, phosphorus, fluorides and other substances, which help strengthen and protect the teeth. While this is a good thing, it also means that we tend to get a deposition of calcium on the teeth. Usually, it is tooth colored and can easily be mistaken as part of the teeth, but it also can vary from brown to black in color
On a more common basis, an ultrasonic instrument which uses tickling vibrations to knock larger pieces of tartar loose. It also sprays a cooling mist of water while it works to wash away debris and keep the area at a proper temperature. The device typically emits a humming or high-pitched whistling sound. This may seem louder than it actually is because the sound may get amplified inside your head, just like when you put an electric toothbrush into your mouth. It’s recommended visiting your dentist every 6 months for then regular checkup & full mouth scaling & polishing.
