There is no doubt that it is good to clean up dental calculus, some people will say that kidney stones and gallstones and other stones are necessary to clean up because they are located in the body and will have an impact on health, so they must be cleaned up, but dental calculus itself is located outside the body, after cleaning up sometimes feel that there are gaps in the teeth or even loose teeth, these ideas are not correct. Calculus itself is due to layer by layer deposition of bacteria and food debris in the mouth, slowly formed calculus-like material, firmly attached to the tooth surface, very difficult to remove, gradually formed and developed so that the periodontal formation of gingivitis and even periodontitis, periodontitis is the primary factor in the loss of teeth in the whole mouth of the elderly, so the calculus must be cleaned. The way to clean calculus is to have a dental professional perform supragingival scaling, which is commonly known as scaling, and scaling is the best way to deal with calculus.
