How about Shanghai Houcheng Stomatological Hospital?

It's my first time to wash my teeth. I don't know how long it will take to wash my teeth in a general dental clinic. Anyway, I remember that I washed my teeth for about 45 minutes, and the doctor washed them very carefully, just a bloody mouth. Oh, my god However, I saw a lot of dental calculus dropped when I gargled halfway, hehe, it was a little comforting. The nurse MM inside said very gently. I think I will go again next time.
