Generally speaking, for people with loose teeth and no underlying diseases, the safety of small clinics with formal qualifications is not a big risk, and basically the safety is guaranteed. For those with serious underlying diseases, the medical conditions in small clinics are relatively less than those in hospitals, and once a serious problem occurs, there may be a lack of appropriate resuscitation measures. Tooth extraction is a means of treating oral and dental diseases, for some teeth that cannot be retained or have little therapeutic significance can generally be given extraction treatment. In general, there is no problem with simple tooth extraction in a dental clinic approved by the regular health department. Tooth extraction is a risky treatment that requires a professional doctor to handle. However, dental clinic is a kind of simple clinic, the medical quality environment and equipment is not perfect compared to hospitals. If the person who extracts the tooth has poor physical resistance, and at the same time there are many kinds of diseases such as heart disease, high blood pressure, diabetes, etc., if there is an unexpected situation during the extraction process, the first aid conditions and measures are limited, and the patient can not get a good rescue treatment. Therefore, the safety of tooth extraction in dental clinics varies from person to person. Regular hospitals should be chosen for treatment.
