First, the culprit of loose teeth periodontal disease periodontal disease is a disease that occurs in the tissue around the teeth, more than 90% of people suffer from this disease. The early stage of the disease has no obvious symptoms, or only gum bleeding, bad breath and occasional chewing weakness and other symptoms, often not taken seriously, such as effective treatment, periodontal disease will gradually aggravate, eventually leading to loose teeth. The disease can be completely healed in the early stages and controlled in the middle stages, while the teeth affected by advanced periodontal disease can only be extracted. Unfortunately, in practice, many people tend to come to the clinic only when the disease has progressed to an advanced stage where the teeth are significantly loose. According to relevant studies, more than 70% of the reasons for tooth extraction in domestic patients are due to periodontal disease. Second, how does periodontal disease occur? The main cause of periodontal disease is poor oral hygiene, unclean brushing, dirt accumulation around the teeth, the proliferation of disease-causing bacteria, the formation of calculus attached to the tooth surface, so that the gums and other periodontal tissue inflammation and destruction of the alveolar bone supporting the teeth, and finally make the teeth loose and fall off, just like a big tree, the roots lack of sufficient soil, as long as a little wind blowing, it can only fall down. So early detection, early diagnosis and early treatment are the keys to periodontal disease prevention and treatment. If you find yourself with some of the following symptoms, such as bleeding brushing, swollen and painful flesh, gum recession, loose teeth, bad breath, etc., beware, you may have suffered from periodontal disease, you should immediately go to a specialist hospital or clinic to avoid delaying the disease and hold the regret of losing teeth. Third, the systemic treatment of periodontal disease includes what steps? 1, supragingival scaling and polishing: supragingival scaling, commonly known as “scaling”, that is, the use of ultrasonic technology to thoroughly remove the calculus exposed above the gums. Polishing, that is, the use of polishing paste and rubber wheel to make the tooth surface smoother, reduce the attachment of plaque and reduce the formation of calculus. Supragingival scaling and polishing is the first step in periodontal systemic treatment and a necessary part of every periodontal patient’s experience, not only that, it is also an important tool in the periodontal maintenance treatment phase. 2. Subgingival scaling and root surface leveling: Subgingival ultrasonic technology and Gracey scrapers are usually used to remove calculus, plaque and endotoxins from the root surface below the gingival level. Root surface planing is one of the most important steps in the entire periodontal treatment and is usually performed under local anesthesia. Currently, the most commonly used root surface leveling method in China is the EMS periodontal treatment system. Since this system is less invasive, safe and fast, effective and can shorten the treatment time during the whole treatment process, most patients are happy to accept this technology. 3. Root canal treatment, tooth extraction and bite adjustment: If the patient has severe periodontal disease that leads to degeneration and necrosis of the dental pulp, which is often referred to as periodontal-pulpal lesions, root canal treatment is required. If the patient’s periodontium has been severely damaged can not be preserved or used teeth need to be extracted, and appropriate adjustment of the occlusal relationship so that the upper and lower teeth even contact, reduce the individual teeth due to excessive occlusal force resulting in occlusal trauma, further aggravating periodontal disease. 4.Surgical treatment: The purpose of periodontal surgery is to remove the infected soft tissue periodontal pocket wall, bone tissue, make the periodontal pocket shallow, promote the formation of new dental bone on the root surface of the lesion, facilitate the regeneration of the damaged periodontal membrane, and connect with the new alveolar bone to form the periodontal attachment. Periodontal surgery is indicated for those with severe periodontal inflammation and deep periodontal pockets, where basic treatment by supragingival scaling, subgingival scraping and root surface leveling is ineffective. Common periodontal surgeries include gingivectomy, flap scraping, bone grafting and guided periodontal tissue regeneration, etc. The specialist will design a specific treatment plan according to the specific situation of each patient. 5.Prosthetic treatment: After the periodontal disease is completely stabilized, the missing teeth should be repaired in time to restore the continuity of the dental arch and reduce the occlusal force of the remaining teeth, and for individual complex cases, such as multiple teeth loosening in the remaining teeth, periodontal splint repair treatment is required. 6, maintenance treatment of periodontal disease: oral hygiene is directly related to the treatment and prevention of periodontal disease, so a patient with periodontal disease must learn the correct oral cleaning method and adhere to it for life. Periodontal disease maintenance treatment includes self-maintenance treatment and in-office maintenance treatment, in which self-maintenance methods generally include effective brushing, flossing or using gap brushes, while in-office maintenance treatment is regular checkups or supragingival scaling at a dental specialty hospital or clinic. Since periodontal disease is a chronic disease that alternates between active and resting phases, its treatment and maintenance need to be maintained for life. For patients with periodontal disease, regular follow-up visits are generally required every 3-6 months to check the effectiveness of self-maintenance or supragingival scaling if necessary.
