The prevalence of periodontal disease increases with age, and the resulting tissue destruction is irreversible, and it is difficult to completely restore normal even after treatment, so that the prevention of periodontal disease is important. Patients with periodontitis tend to have poor oral hygiene, which is also responsible for the occurrence of most oral diseases. In addition to the common chronic periodontitis, there are many types of periodontal diseases, such as simple gingivitis, acute necrotizing gingivitis, pregnancy gingivitis, juvenile periodontitis, rapidly progressive periodontitis, and pre-pubertal periodontitis. The common symptoms of periodontal disease are several: 1. bleeding of gums during brushing and flossing; 2. often have an unpleasant odor (halitosis); 3. swollen and soft gums; 4. the teeth are loose.
Regardless of the periodontal disease, if not actively prevented or treated, inflammation progresses in a chronic progressive manner, unconsciously destroying periodontal health, and a detailed treatment plan is made for sequential treatment. Periodontal disease is controllable through careful diagnostic design and systemic treatment.
