The main methods of tooth cleaning are ultrasonic tooth cleaning, sandblasting tooth cleaning and tooth polishing. Ultrasonic dental cleaning is to loosen dental calculus by ultrasonic vibration emitted by ultrasonic dental cleaner, and then remove dental calculus by scraper. Ultrasonic cleaning is mainly to remove dental calculus. Ultrasonic cleaning is difficult to remove the smoke and tea stains in the pit and fissure of teeth or between teeth, so the method of sandblasting cleaning must be adopted. Sandblasting is to spray a solid salt on the tooth surface with high-pressure airflow to remove stains on the tooth surface and between teeth. The salt will melt in the mouth. Generally, sandblasting is carried out after ultrasonic cleaning, and the effect is remarkable. Polishing is to use polishing paste to grind the surface of teeth more smoothly, make the taste more comfortable, and prevent dirt from adhering.
