Theoretically, a good porcelain crown usually works for more than ten years, which is durable and stable. In real life, the working life of porcelain fused to metal crown is higher than 2 or 30 years, which is optimistic for patients. However, many braces cannot work so long, and their working years are still related to many premises. For example, your level of care, the eugenic technology of the material itself. Generally speaking, if the tooth body is seriously damaged, it is recommended that you replace it as soon as possible. The use time of dental braces is mainly related to objective factors such as patients' tooth conditions and follow-up maintenance. If maintenance and subsequent cleaning are not paid attention to, or hard blocks are bitten with crowns, the working life will be shortened.
How often is the porcelain crown replaced?

Generally, the average life of porcelain crowns is 5-10 years. But porcelain crowns are not 100. It is more important to carefully protect (reduce losses) and regularly follow up, regardless of the doctor's technology and materials. To install porcelain teeth, you need to grind the missing teeth on both sides small, and then put a tooth cover on them. The restored teeth need good adjacent teeth to occlude. Just like porcelain teeth repair, because the incisors are inflamed, they do not need to bear a lot of burden, and they do not need to bite any hard blocks, so porcelain is also very good, and the doctor's treatment is no problem.
Prolong the service life of porcelain teeth
① In order to increase the service life of porcelain crowns, attention should be paid to oral hygiene. The combination of porcelain crown and tooth is very easy to collect bacteria. If not cleaned, food residues will gather here, causing gingival redness and tartar. Over time, the gingival mucosa became swollen and painful, and the porcelain crown had to be pulled out again.
② Don't bite solid things! The porcelain crown teeth are hard and brittle, and the direct bite force usually only reaches 1/20 of the natural teeth. Therefore, the person who installs the porcelain crown should avoid biting solid food, such as hard walnuts, bones, crab claws, etc., to avoid damaging teeth.
③ After the porcelain crown is completed, we should pay more attention to tooth protection. We should go to the clinic every six months for inspection. If any problems are found, they should be repaired in time. Can't the fate of implant teeth be prevented after the installation of porcelain teeth? Just now, I also mentioned the service life of porcelain crowns and how well they are maintained. They also need to be replaced once every 10-15 years. But in fact, do you want to replace porcelain crowns or implant teeth? The answer is not necessarily!

Porcelain fused to metal crown is better than dental implant
If your root is better preserved, you can still install a porcelain crown directly. If the root injury is serious, only implant teeth can be considered! Many people will say that the porcelain crown will be damaged in the future, * good direct planting teeth, 100!
Generally, porcelain crowns are more suitable for tooth cracking, while implant teeth tend to fall off. The scope of application of implant teeth and ceramic crowns is different from the indications, and must be selected according to the patient's own premise, which is naturally related to the duration and cost - if the appearance and shape of the teeth themselves are complete, ceramic teeth can be installed for about a week, and the extraction of implant teeth can be completed at least 3~6 months, which requires film. CT、 Two operations and a series of treatments. If you want to quickly obtain a beautiful image and use teeth, * install porcelain teeth~
Price of porcelain teeth

Cost factors: general metal crown porcelain teeth are relatively cheap, and the whole porcelain crown is relatively expensive. According to the price of different brands, it varies from hundreds to thousands of yuan. The cost of dental implants is very expensive, including in China, South Korea, France, the United States, Sweden, and the price has almost risen one by one, basically more than thousands of yuan, so tens of thousands of teeth are also very common.
In addition, although there is no definite service life standard for implant teeth, their service life depends on the protection in the middle and later stages. If regular physical examination is carried out on time and dental cleaning is carried out every 6 months or so, it can really be used for a lifetime! If you indulge in diet and do not pay attention to the health of teeth, the implant teeth will become loose and fall off. Therefore, both porcelain teeth and implant teeth can eat good teeth! As long as you pay attention to the protection of oral care and check on time, you don't need to worry too much~
Several situations of removing porcelain dental braces
Many friends who have made porcelain teeth know that it is normal to use porcelain teeth for about 10 years. However, if the porcelain teeth are not good, there are still chances of black, inflammation, odor, tooth allergy and other symptoms. Therefore, no matter how long the porcelain teeth have been made, if this problem occurs, they should be removed and repaired immediately. There are about four cases in which the porcelain tooth socket must be removed again:
(1) Porcelain crowns and alveoli are not sealed and bacteria are deposited

Unqualified tooth wear, incomplete tooth models, and unqualified manufacturer processes will lead to large gaps between crowns and alveoli. After two or three years of application, it has become a storage place for bacteria and viruses! Brush teeth and use mouthwash. It's no use flossing. Bacteria and viruses accumulated between porcelain teeth and real teeth enter the crown and slowly erode the primary teeth, leading to caries of the primary teeth. Over time, primary teeth are more likely to have basic caries.
(2) Metal oxide of metal porcelain tooth causes tooth bed discoloration
The black problem at the neck edge of the porcelain prosthesis makes the gums black, which is a common adverse reaction in the production of porcelain teeth made of non precious metal materials (nickel chromium, cobalt chromium, titanium alloy) and is difficult to solve. The reason for gingival staining is the oxidation between the general metal base crown and gingiva. In addition, this porcelain tooth must be removed and changed again, or it will cause gingival inflammation, which will slowly develop into periodontal disease, leading to gingival atrophy and loss.
(3) The quality is unqualified, and the metal is exposed in the crown

Some people's porcelain teeth are broken and still in use. This is not correct, because it is not only ugly, but also the metal has been rubbing with the food in the mouth for a long time. It is not clear whether there are shortcomings in chemical changes under the action of the mouth itself, so it is recommended to remove it as soon as possible.
(4) Excessive stimulation of dental pulp in porcelain tooth production
Install porcelain teeth, but hot and cold alternate hot and sour, but do not want to eat more, it will hurt every once in a while. Why is this? It is mainly because the doctor grinds the teeth too fast in the production process, which stimulates the dental pulp too much, and the dental pulp is still in the state of hematoma. Before making porcelain teeth, we must evaluate the condition of the periodontal bed. If there is obvious abnormality, the periodontitis treatment must be carried out first, and then the porcelain tooth repair can be carried out after the gingiva recovers.
