Scaling and polishing are two of the most common dental procedures intended for maintenance of dental hygiene. A person who's suffering from bad breath may think about deep cleaning with scaling and polishing.
Scaling is a dental process that involves removing the calculus deposits or stains on the teeth. The dental hygienist usually begins with an ultrasonic instrument that sends vibrations to the teeth to loosen the more visible and large deposits. The instrument emits cooling mist made of water to wash the debris away as the procedure goes on.
Polishing, on the other hand, is the process of smoothing the teeth as scaling can make the teeth feel rough.
