Pain is a relative concept. Some people have a relatively good tolerance for pain and do not think it is very painful after wisdom tooth extraction. However, some people have a low threshold of pain tolerance and consider the pain after wisdom tooth extraction to be very intense. Moreover, wisdom tooth extraction is closely related to the depth of wisdom tooth growth and the difficulty of extraction. In the case of relatively simple wisdom teeth, they can be removed by simply using dental jaws and forceps, and the pain is not particularly noticeable. However, if the wisdom tooth is a relatively complex buried obstructed wisdom tooth, a series of operations such as flap, bone removal and root splitting are required, which is relatively more traumatic and will cause more severe swelling after surgery, so the pain of this kind of wisdom tooth is heavier.
