The whole process of normal wisdom teeth removal is divided into preoperative preparation, intraoperative removal, postoperative treatment and precautions. 1. Preoperative preparation: Before normal wisdom teeth extraction, patients need to take X-ray film, the doctor to check the shape and location of wisdom teeth to determine the plan. After the patient’s mouth is cleaned, the doctor will use local anesthesia drugs to perform oral local block anesthesia. 2. Intraoperative extraction: After the anesthesia takes effect in about 5 minutes, the doctor cuts the gums and turns the flap to expose the wisdom teeth. Immediately expand the periodontal space with dental tines to lift the bone resistance of the root bone tissue, some patients need to lift the resistance of neighboring teeth to reduce bone resistance, split crowns and root splitting, etc., and then remove the wisdom teeth. After wisdom teeth extraction, we should check whether the teeth are intact or not, carefully inspect the extraction wound and remove the debris. 3. Post-operative treatment and precautions: Wisdom tooth extraction will create an empty nest defect, also known as the extraction socket. The surgeon will remove the debris inside the extraction socket so that blood can fill the socket and partially suture the gums. After suturing, a sterile cotton ball will be used to apply pressure to stop the bleeding for about 30 minutes. After that, there will be a doctor’s order or a nurse to tell the postoperative precautions, such as do not brush your teeth and rinse your mouth for 24 hours after the operation, cold compresses and so on. The above is the whole process of routine normal wisdom tooth extraction, and patients are advised to consult the local hospital.
