The fear of extraction of obstructed teeth makes many patients doubtful about the extraction process and the corresponding method. Currently, many hospitals have adopted the microdynamic system extraction method, which has made it possible to significantly reduce the extraction time of such complex teeth. The minimally invasive approach assisted by the implant machine system used has minimized the trauma of the extraction and increased the efficiency of the procedure. However, not all patients are able to complete the procedure in ten minutes. The morphological variation of obstructed teeth is large, and when a few complex cases such as malformed curved roots, hypertrophic roots, root-bone adhesions, and overly buried deep teeth are encountered, the time required for the surgery is 30 minutes or more. Everything is difficult or easy, and extraction of blocked teeth is a delicate surgical procedure that cannot be measured by analogy in the form of a sprint race for time. It is the goal of the surgeon to remove the tooth with the smallest incision and the least possible trauma. Regarding the post-operative reaction after extraction, it varies from person to person and from tooth to tooth under the premise of minimally invasive extraction! The same surgeon and the same surgical method have very different reactions from one patient to another. Some people feel no pain or swelling, others feel mild swelling and pain, and a few patients react violently and severely. Generally speaking, young women react more severely than middle-aged men after surgery. For example, many people say that one side does not hurt after surgery and the other side hurts after surgery, which is a common phenomenon. However, when it comes to a few complicated cases such as malformed curved roots, hypertrophic roots, root-bone adhesions, overly buried deep teeth, etc., the surgery takes a long time, and even if the trauma is small, the postoperative reaction is usually very serious, and the incidence of swelling and pain is almost 100%, accompanied by restricted mouth opening, fever, etc. The possible reactions will be explained by the surgeon after the surgery and will be dealt with by appropriate anti-inflammatory and pain relief methods, so the patient does not need to worry too much.
