When local pain occurs after the anesthesia medicine has failed, two methods of oral pain medication and local cold compress treatment can be used to relieve the pain, as follows: 1. Oral pain medication: Commonly used pain medications include ibuprofen or fen-phen, which can relieve pain to different degrees after tooth extraction. 2. Local cold compress: Local cold compress is used to reduce swelling and pain, especially when wisdom teeth or molar teeth are extracted. The tooth extraction process may cause different degrees of soft tissue and hard tissue damage, and local swelling and pain will occur after the extraction, so local cold compresses can be used to stop pain and reduce swelling. The specific method is to use a medical ice pack or chilled bottled mineral water to apply a local cold compress to the cheek on the corresponding side for about 10-20 minutes to stop pain and reduce swelling.
