Often patients will ask: “porcelain teeth in the end can be used for how long”, from the clinical point of view, some with three or five years, some with more than ten years or intact as before. The author believes that porcelain teeth can be used for how long with many factors, the life of each porcelain teeth is different. In addition to the material, production process, the basic condition of each person’s teeth is different, which is an important factor in determining how long porcelain teeth can be used. If each tooth has a fixed root, and the root is very firm, there is no basic dental disease, then the porcelain teeth with decades are no problem. On the contrary, if the patient’s roots are damaged, missing teeth, or often commit periodontal disease, even if the best quality gold porcelain teeth and zirconia porcelain teeth, more than ten years. I reminded the majority of patients, made porcelain teeth is not the same as once and for all, careful protection is very important. So how to care and maintenance of porcelain teeth? Although porcelain teeth have the advantages of strong and wear-resistant, due to the factors of raw materials, the surface of the porcelain layer are relatively brittle. Most porcelain teeth are limited by the degree of force, once more than this strength, it is easy to damage the porcelain teeth, affecting its life. Therefore, the first wear should eat soft food, it is best not to use porcelain teeth to chew hard bones, eat crabs, hazelnuts, walnuts and other hard food. Porcelain teeth and the combination of the abutment teeth that porcelain teeth near the gum area of the jaw and neck edge is most likely to hide food debris and breeding bacteria to produce plaque, the formation of tartar, should pay attention to cleaning, between the teeth can be flossed clean, and regular check-ups to the hospital, dental cleaning. Porcelain teeth are generally not discolored, to ensure the hygiene of the space between the teeth, especially pay attention to the control of periodontitis, so that the dentures do not fall off the real teeth in the end. As for the front teeth, be careful not to often use hard objects to bump them, or long days will be chipped porcelain. In addition, the initial period of wearing porcelain teeth compared with the dental set, the upper and lower cusp alignment is different, to eat slowly, and gradually develop the correct chewing habits, so as not to bite the cheek, tongue mucosa. At present, the porcelain teeth made of nickel-chromium alloy is a widely used material in clinical practice, but due to the limitations of the porcelain teeth themselves, some porcelain teeth may inevitably cause the phenomenon of gum margin black line. The author recommends close observation and regular check-ups of such porcelain teeth in the hospital. If you find signs of gum black line, immediately replace the porcelain teeth made of other alloys while gum treatment. It is also recommended that patients consider using porcelain teeth made of precious metals such as gold alloys for the first time to avoid gum blackening. If the use is limited due to the high price, then applying gold powder on the edge of the porcelain teeth made of nickel-chromium alloy is an economical, convenient and good solution to the problem of black line. Then there is talk about periodontal disease of the teeth with porcelain teeth. Periodontal disease teeth after timely and effective treatment, some can be restored through porcelain splints to retain or extend the use of the affected teeth for a long time, which plays a positive role in preserving the alveolar bone and maintaining the integrity of the teeth. The purpose of this method is to reduce the burden on periodontal support tissues, fix loose teeth, disperse the joint force, control pathological loosening and displacement of the affected teeth, give physiological rest to periodontal tissues, create conditions for periodontal tissue healing, improve aesthetics, and enhance chewing performance. Patients must maintain long-term oral hygiene and periodontal hygiene to avoid aggravation of periodontitis. Perform regular review. Some patients only focus on the aesthetics of the front teeth, the upper and lower front teeth for porcelain dental splints after restoration, not timely restoration of multiple missing time of the back teeth, resulting in the front teeth or one side of the back teeth are overburdened, the phenomenon of chipped porcelain. In short, although porcelain dental function recovery is better. But there is no porcelain teeth equal to real teeth. Do not think that after the porcelain teeth will never have problems. Porcelain teeth should pay attention to careful maintenance and maintenance, pay attention to oral hygiene, avoid using porcelain teeth to bite too hard food and develop the correct chewing habits. Also regular review, there are problems in time to solve. Each person’s dental situation is constantly changing. Therefore, the teeth should also be regularly checked, maintenance and maintenance. While being beautiful is important, health still has to come first. To achieve the dual purpose of health and beauty, choose the regular hospital as much as possible, because in the regular hospital dental implants, there is a certain period of warranty repair period, in order to facilitate the follow-up, should be properly stored in the medical records. Visit to a professional doctor, careful consultation, careful consideration before making a decision to ensure the best cosmetic dental results and long-lasting dental health. Make the porcelain teeth benefit you for a lifetime.
