The removal of calculus, which generally means that larger stones have been removed on their own, is generally a major periodontal problem in this case, with obvious symptoms of gingivitis or periodontitis, and systematic periodontal treatment needs to be given. The first thing to do is a supragingival cleaning, also known as scaling, to remove larger chunks of calculus and plaque from the mouth, which is then supplemented by manual subgingival scaling, also known as subgingival calculus removal, to treat the subgingival calculus again. After the two processes are completed, if good results are still not achieved, periodontal surgery can be considered as a systematic treatment of the periodontium. However, this is a long process and patients are advised to take longer time and perseverance to complete the entire treatment process.
