The principles of treating gum pain are the same: remove the cause (plaque, tartar, tartar) and prevent the progression of the disease (careful and proper oral hygiene care, including brushing, flossing, toothpicks, interdental brushes and other aids). Regardless of the type of periodontitis, it should be “lifelong treatment, lifelong maintenance”: 1. Thorough scaling and scaling by the doctor to remove the cause of inflammation (plaque and tartar, soft tartar); 2. Your oral hygiene maintenance at home is especially important because plaque and soft tartar are deposited all the time. Ensure complete and thorough brushing twice a day to remove plaque and tartar, supplemented by flossing, toothpicks, and interdental brushes to clean the interdental space; 3, regular review and maintenance at the hospital, generally individuals with chronic periodontitis and good self oral hygiene can go for professional maintenance once every 6-12 months, patients with aggressive periodontitis need professional maintenance once every 3 months, including supragingival scaling, and necessary gingival subgingival scaling as necessary. The core of the treatment of periodontitis is to remove the cause, control the inflammation, and keep the lesion from progressing.
