Dentistry in big hospitals is expensive and poor. It's dark.
For example, Hainan Hospital.
If you want to go to the dentist's office, I recommend going to the dentist's office next to Longshepo Market after going down the mountain in Haikou.
I went there to have braces made, which was much cheaper than the provincial hospital and my teeth were better.
See if you can give me the best answer. I hope it helps you.
