The same affected tooth, the same degree of looseness, the same periodontal disease, if you go to different hospitals, different doctors will appear “extraction” or “retention” two completely different results. To extract a tooth is equivalent to a “death sentence”, while to keep the tooth and give treatment is equivalent to giving “life” to the affected tooth, which is a completely different result. If we discuss this issue and consider that one of them must be wrong. Does that mean that one of the doctors must be wrong and should be liable for medical malpractice? The answer is no. The fact is that the “retention” or “extraction” of a loose tooth with severe periodontitis is a complex dental multidisciplinary issue that has been subject to different views and even great differences. The recognition of extraction or retention of loose teeth should be a process of evidence-based medicine. Depending on the patient’s wishes, financial ability, and the doctor’s mastery of evidence-based medicine, the criteria for extraction are different and influenced by many aspects. In recent years, with the socio-economic development and the maturity of the implant technology, many doctors, including those from prestigious universities nationwide, prefer dental implants for patients with missing teeth. However, I am very cautious about dental implants for patients with periodontal disease in clinical practice! It is good for the hospital and the doctor – it increases the income, but it increases the patient’s pain and financial burden, which I think is not in line with the concept of evidence-based medicine! I choose a permanent method for this type of missing teeth, a one-time treatment and restoration of periodontal disease patients’ teeth, so that they can be retained for life. My unique design plan has been certified by the basic theory of dentistry, and has been clinically verified by many years of clinical periodontal disease patients’ dental treatment and veneers, and has received excellent prognosis and veneer results for periodontal disease patients’ teeth. I have made personalized treatment and veneer designs for the criteria of “retention” of loose teeth, and in the treatment of clinical periodontal disease, we have adjusted the dental treatment plan according to the tooth’s response to the treatment, and obtained the effect of lifelong retention of the affected teeth. As we all know, the internal cause is the fundamental reason for the development of things, and the retention of loose teeth with periodontal disease is a comprehensive project involving various specialties such as oral imaging, endodontics, periodontology, mechanics and biomechanics, prosthetics, orthodontics, health care and prevention, etc. The most fundamental factor in deciding between “extraction” and “retention” is of course The most fundamental factor that determines “extraction” and “retention” is, of course, the degree of development of medicine itself. When a doctor with a high level of medicine and a famous doctor makes a design for extraction or retention of a loose tooth, the concept always surpasses most doctors, and the plan will be more favorable to the patient, always preserving the tooth that most doctors want to extract, so that the patient can get a permanent, better, or perfect veneer. We now have a unique method to permanently preserve loose teeth (of course, it depends on the specific situation of the teeth to determine, take oral special CT to check the periodontal situation of the loose teeth to make treatment plans), avoiding the treatment of veneering while the teeth are loose again in a few years, then extracting and veneering again, until all the teeth are extracted, try to preserve your own natural teeth, so that you can enjoy the food on earth!
