There is no trick to removing calculus on your own, and removing calculus on your own runs the risk of damaging your teeth. It should be removed by ultrasonic scaling, subgingival scraping and tooth polishing. 1. Ultrasonic scaling: Using the high-frequency oscillation of the ultrasonic scaler, it is usually able to effectively remove the pigmentation, soft tartar, and calculus around the teeth without damaging the teeth. 2. Subgingival Scraping: For the calculus below the gums, ordinary scaling is often unable to clean it up, so it is necessary to perform subgingival scraping, in which the professional doctor removes the calculus by means of manual instruments. 3. Teeth polishing: after the removal of calculus through the above two ways, the teeth can be fully polished, so that the surface of the teeth is more polished, to slow down the growth of calculus has a certain effect. The removal of calculus needs to go to a regular hospital operated by a professional doctor, and can not be blindly removed to avoid damage to the gums and teeth.
