There is no such thing as the easiest way to get rid of dental calculus, at present, you can choose to do a good job of daily care, and carry out supragingival cleaning, subgingival scraping. 1. Daily care: dental calculus need to pay attention to oral hygiene, every day after meals, insist on rinsing and flossing to clean the teeth adjacent to the surface, to avoid food clogging, and insist on morning and evening brushing on time. This can prevent the aggradation of dental calculus, but can not be removed. 2. Gingival cleaning: you can choose to use ultrasonic scaling or manual scaling to clean up dental calculus, through sandblasting the surface of the teeth to clean up the pigmentation, but also to remove the plaque attached to the surface of the teeth. 3. Subgingival Scraping: It can be combined with supragingival scaling, which is operated in the same way, and after cleaning, root planing will be carried out to soften the calculus on the surface of the teeth to achieve the purpose of smoothing. Subgingival scaling is suitable for patients with periodontal disease or individual teeth with subgingival calculus. Before the scaling procedure, the doctor needs to know whether the scaling patient has any underlying diseases, whether she has a pacemaker, whether she is menstruating or not, and should truthfully inform the doctor of these conditions, so that the doctor can judge whether it is possible to carry out the treatment or not.
