As far as I know, there are three places to do it. The first is the central hospital dentistry, which is more formal and expensive. The second one is the Stomatological Hospital near Pingyuan Shopping Mall, where a friend of mine made corrections, and the price was not clear. Third, there is a dental clinic next to the battery factory. It seems to be in the battery factory hospital. I can't remember the name. The doctors there have good skills and relatively cheap prices. I did it there a few years ago and everything has been corrected. I remember that it only cost more than 3,000 yuan at that time, and the effect was not bad, but the price now is far from that of a few years ago, and it should be a lot more expensive. You can go to these three places for consultation ~
