Ultrasonic scaling is now often used clinically for dental cleaning. The cost of ultrasonic scaling is$5 per tooth, and the cost for a full mouth of 28 teeth is$110 per tooth at 20. After applying the ultrasonic scaler for scaling, the tooth surface also needs to be polished, also known as a dental surface polishing procedure. This operation costs the same as ultrasonic scaling,$5 for one tooth, and a full mouth of 28 teeth is charged at 20, usually$110. So it adds up to about$220 in total. Generally the price of scaling in most cities is about 220 yuan, but there are some small clinics where the cost of scaling may be lower, it is about 100 yuan, but it is recommended to go to a regular hospital for scaling.
