Some people think that “toothache is not a disease”, so neither pay attention to oral hygiene and health care, suffering from dental disease is not timely treatment; often hear people say: “my teeth are not good, I’m ready to after the teeth do not work and then all dial off, and then installed a full set of dentures”; more people in order to quickly relieve the toothache and rashly dial teeth. Some people even dial their teeth rashly in order to relieve toothache quickly. However, we would like to caution those patients who ask for tooth extraction to think twice before doing so. 1, “Dental health is the embodiment of the health of the whole body” Only through the sound teeth fully chewed food, can be fully digested and absorbed by the gastrointestinal tract. Moreover, straight and white teeth as well as clear and pure speech are the foundation or catalyst for good interpersonal communication, social life and work. There are two sets of teeth in a person’s life – milk teeth and permanent teeth, with 20 milk teeth and 28-32 permanent teeth. Although the number of teeth may seem large, the upper and lower jaw teeth must work together in order to function. When categorized by function, there are only 1-3 pairs of teeth that perform a particular function. If a tooth in the upper or lower jaw is missing, the function of the corresponding tooth will be lost, so every tooth is equally important to us. 2. “It seems simple, but it is not easy” Secondly, it seems simple and convenient to have a tooth extraction, but not to mention the risk and pain of surgery, the restoration (veneer) in the future will be a very laborious and costly thing. The tooth is always to be repaired, the long time without repair of missing teeth, not only cause chewing function decline, but also will lead to neighboring teeth displacement, jaw teeth elongation, and then cause temporomandibular joint dysfunction, facial reshaping, and so on. Today’s restorative technology is changing rapidly, in the regular or large hospitals, a variety of new materials, new technologies are constantly applied to the clinical. Porcelain crowns and bridges, precision attachments, sleeve crowns, magnetic retainers, dental implants and other new restorative techniques have been gradually selected by doctors and patients. Each new technology is an improvement of the previous technology, but each kind of restorations and technology has certain indications and advantages and disadvantages, and the cost also varies a lot, in the end, which one to choose, need to be based on the patient’s oral cavity, the use of the requirements and the economic situation to decide. 3. “Don’t trust dentures too much” As far as the current technology is concerned, even the best restorations are not as good as your own healthy teeth. A prosthesis is nothing more than a prosthesis, a helpless but necessary choice. Not to mention the fact that the quality of the restorations is a big unknown, depending on the design of the practitioner, the level of denture fabrication, the materials used, and the patient’s adaptability. After spending time and money and suffering, you may not be able to get a pair of dentures that are comfortable and work well.
