Gum recession caused by periodontitis is clinically difficult to recover. In the case of gum recession, surgical repair can be attempted, for example, the gums of the palate can be used for gum grafting of the receding gums, which is relatively effective for traumatic gums, but is less effective for gum recession caused by periodontitis. Clinically, it is still very difficult to restore receding gums due to periodontitis, but this does not mean that there are no treatment options for periodontitis. Once the symptoms of periodontitis appear and the gums start to recede, we need to go to a professional dentist as soon as possible and apply supragingival scaling and subgingival scraping combined with root planing to remove the periodontal calculus and plaque, so as to remove the causes of periodontitis, avoid further development of periodontitis, and at the same time maintain Through these methods, periodontitis can be stopped from developing further, and gum recession can be stopped from one side.
