A question often asked by patients with periodontitis is what medications should be taken for periodontitis? In fact, periodontitis medication plays only an auxiliary role and should not be abused, otherwise it will have adverse consequences. Periodontitis is a chronic inflammation of the gum and periodontal tissues, a destructive disease characterized by the formation of periodontal pockets and inflammation of the pockets’ walls, the resorption of the alveolar bone and the gradual loosening of the teeth, which is the main cause of tooth loss in adults. The disease is mostly caused by plaque, tartar, food impaction, poor restorations, bite wounds, etc. The gums become inflamed and swollen, while the plaque buildup increases and expands from supragingival to subgingival. Due to the characteristics of the subgingival micro-ecological environment, the subgingival plaque harbors a large number of more virulent periodontal pathogenic bacteria, such as Bacillus gingivalis. Treatment of periodontitis The treatment of periodontitis is based on local treatment, firstly removing the tartar above the gums (medically known as supragingival tartar), then removing the tartar in the periodontal pockets (i.e. subgingival tartar), and scraping the diseased dental bone containing a large amount of bacterial toxins in the periodontal pockets, after these treatments, the gum redness and swelling can subside, and the gum bleeding and pus overflowing from the periodontal pockets can disappear. The first stage is the basic treatment stage, using the conventional treatment methods of periodontal disease, removing or controlling the pathogenic factors, including oral hygiene habit cultivation including brushing, flossing, gap brush use, correcting bad habits such as mouth breathing, extracting teeth with poor prognosis and unfavorable restoration, supragingival scaling, subgingival scaling to remove plaque and tartar, appropriate selection of antibacterial drugs to control inflammation as an auxiliary treatment, and adjusting the bite and jaw. The second stage is periodontal surgery and fixation of loosened teeth. The third stage is permanent restorative treatment, which is usually performed 2-3 months after surgery. The fourth stage is the maintenance treatment stage, every three months to six months, which includes checking plaque control, hygiene promotion, and radiographic examination for further development of treatment plan. The first thing you need to do is to take a look at the actual periodontitis treatment.
