I made it up in the people's hospital a few days ago. It is made of resin. For the first time, two of them charged me more than 300 yuan, and only one of them made up, because there was a worse one. It is said that it is very painful to press and observe, so I can't make it up. Then the second check collected more than RMB 100, and it still hurts. I'm waiting for the third pain. . . . If there are no serious symptoms, it will be one or two hundred yuan. My first tooth has been filled a little, so I can't see it. According to the experience of people who have been there, if it is obvious, it is better to watch it early.
