Don't go to Xiling stomatological hospital. It's terrible. Last time I did a root canal at Du's, it hurt for several months. I went to see him several times in the middle and said nothing. It will be fine in a few months. Other doctors didn't give me a rest when he was away, so I had to wait for him to come and see me. Really? Too bad. Later, I saw it in another hospital and didn't give me a root canal. Don't go to Xilingkou even if you die.
