Teeth are not like other things, you should take them seriously. You can go to Harbin Forestry General Hospital, where there is a special dental branch. His family has its own dental school. I have been treating my teeth in his house since I was a child. His family is professional and his dentistry is good. Can his treatment cost be cheaper than forestry hospital? Both hospitals are in the power area. You can check the address online, one in Wangzhao New Village and the other in Heping Road, for reference only.
