I don't recommend you to go to Hangu District for tooth extraction, whether public or private, because tooth extraction is not a difficult operation, but it requires a high quality of dentists, and practitioners who have not received special training and exercise are very likely to leave hidden dangers for patients. For example, the dentist's appearance fee is more expensive, because their clinic can't be solved by a few chairs at a table. Just a recliner (I don't know the specific name) for patients is very expensive, and doctors need to use new and sterilized complete sets of instruments (including gloves and various metal tools) for each patient, and take photos before tooth extraction to accurately determine the parameters of tooth extraction. Hangu district doesn't have this level now. I usually go to a big hospital or stomatological hospital in Tianjin. I just pulled my teeth at the Stomatological Hospital of Medical University. I soon relaxed (I couldn't open my eyes), I could eat soon after anesthesia, and I didn't feel anything (abnormal) the next day. I feel that this hospital is very professional and of high quality, and of course the appearance fee is also high. I'll stop here for your reference only.
