Your present situation needs to be corrected. If only the teeth are irregular, you can do orthodontics, or you can do porcelain for individual irregular teeth. The difference is that it takes a long time to correct the deformity, but porcelain doesn't take that long. However, the indications of porcelain are limited. If your individual teeth are badly uneven, it won't work. I can't see your teeth now, so I can't say which method is more suitable. But these two methods cannot be completed in one day. It is obviously inappropriate for you to go to other places instead of local treatment. If you really think the price in Shanghai is unbearable, then consider whether you can return to Jiangdu regularly. If you can make porcelain, it will take about 2 to 3 times, and the number of orthodontics is far greater than that of porcelain. As for how many times and how long it takes, it depends on your teeth. It's hard to say until you see your situation. When choosing a hospital, it's best to choose a regular local stomatological hospital first, because a regular hospital can ensure the curative effect and disinfection of instruments, so that you can avoid all immeasurable consequences caused by improper treatment. In terms of price, orthodontics is more expensive, while porcelain is relatively cheaper. Porcelain teeth are charged per tooth, which may need to be handed in at one time for orthodontics. As for the specific figures, every hospital in every place may be different.
I want to give you a suggestion. I went to the best stomatological hospital in Jiangdu on May 1 day to ask the prosthodontist if it was suitable for making porcelain. If it is not suitable, go to the orthodontics department, and the doctor will tell you how many times you need to come. You can explain your situation to the doctor and see if the doctor can arrange time for you. If the price is right, you can also ask if you can give a discount.
Pay attention to go to a regular hospital for treatment, not just for the sake of cheapness. Seeing a doctor is not like shopping. If something is not satisfactory, you can throw it away. If something goes wrong after dental treatment, it will be difficult.
