Gingivitis and periodontitis are two different diseases and there are differences in the treatment of the two. Gingivitis is a localized inflammation of the gum tissue caused by plaque and other factors. Gingivitis caused by plaque may progress to periodontitis if left uncontrolled. Gingivitis may present with symptoms of swollen, red gums and may be accompanied by bleeding gums. Periodontitis is an inflammation of the periodontal tissues, which may result in periodontal pocket formation, alveolar bone resorption, tooth loosening, and even tooth loss in severe cases.1. Gingivitis: Patients with gingivitis should first seek medical attention to remove plaque, tartar and other irritants through scaling. You can use chlorhexidine or iodine for local anti-inflammatory treatment as prescribed by the doctor. Patients with poor gum shape and fibrous gingival hyperplasia can have their gum shape corrected using surgical methods such as gingivectomy or gingivoplasty. If it is a large gestational gingival tumor, you can follow the doctor’s instructions for removal surgery; 2, periodontitis: you can remove all the bad restorations, tartar and other pathogenic factors from the periodontitis site through scaling and scraping to prevent further deterioration of the disease. In milder cases, such as the presence of inflammation and bleeding, but no pus or only a small amount of pus, and shallow depth of periodontal pockets, etc., medication such as amoxicillin, cephalosporin, and metronidazole can be used. In severe cases, such as more periodontal pus, deep periodontal pockets, and more alveolar bone resorption, gum scraping, periodontal flap surgery, and soft tissue grafting can also be performed. In addition, acute periodontitis may be accompanied by abscesses, which should be incised and drained, and assisted with antibacterial and anti-inflammatory drugs to help the wounds heal. In addition, patients should pay attention to oral hygiene on a daily basis, use proper brushing and pay attention to rinsing after eating to help recover from the disease and also prevent the occurrence of other dental diseases.
