Extraction of the affected tooth: The doctor needs to use anesthetics to provide local anesthesia to the affected tooth. After the anesthesia takes effect, a separator needs to be used to separate the gums to prevent tearing, and then a turbine handpiece or ultrasonic bone cutter will be used to remove the distal and middle alveolar bone and other resistances, and then a dental tappet will be used to loosen the affected tooth, and the extraction forceps will be used to take out the affected tooth. 3. Suture to stop bleeding: Since the extraction wound of the wisdom tooth is relatively large, the surgeon needs to use surgical suture to close the wound after extraction to prevent excessive bleeding and to promote early healing of the wound. The above describes the basic steps for removing a wisdom tooth in the middle of the distance, but individual circumstances and the doctor’s operating habits are different, may lead to different steps, it is best to go to a professional dental hospital for treatment.
