I made it in Chongqing, and the price is not cheap, but it may be more expensive in Beijing. You can search online. I have searched. There is a good stomatological hospital in the north (it seems to rank second in the country)-just enter "National Famous Stomatological Hospital" in the search bar.
It doesn't matter if the price is expensive. Even if you don't have that much money for a while, you can wait for a while, but you must find a regular hospital. The dental clinic on the street is cheap, but the quality is poor. I know something about this because I have done it twice. )
Check online first, and then make a decision on the rest.
I wish you a bright smile at an early date. _
