Tartar is a hard adherent formed by calcification of plaque in the mouth over a long period of time, and is generally the primary cause of gingivitis and even periodontitis. Regular brushing or flossing cannot make it fall off quickly, so the most common clinical method to make tartar fall off quickly is scaling, which is also called supragingival scaling. The most common method of supragingival scaling is called ultrasonic scaling, which involves the use of ultrasonic waves to vibrate the gums and periodontium to make the tartar fall off quickly. If there is still subgingival calculus, it is also necessary to supplement with manual subgingival scraping to achieve better tartar removal, so supragingival scaling plus subgingival scraping is the best way to get rid of tartar quickly.
