The way to remove tartar is through full mouth ultrasonic scaling, which works mainly by resonating and shaking off our tartar, without any harm to the teeth themselves. If there is not only tartar on the gums, but also a large amount of plaque and tartar under the gums, a simple cleaning will not solve the problem. In this case, systematic periodontal treatment is needed to thoroughly remove the plaque and tartar hidden in the gum flesh through subgingival scraping and root planing, and this part of the calculus is the biggest cause of the real resorption of the alveolar bone. With the above treatments, if there is still a small amount of tartar attached to the root surface that cannot be removed, periodontal surgery is also required at a later stage. Therefore, it is important not to delay too long after having tartar, which leads to excessive accumulation of tartar.
