The whole process of wisdom teeth extraction is mainly divided into preoperative preparation, extraction surgery, postoperative care and other steps, which need to be operated by a professional dentist. 1. Pre-operative preparation: Before wisdom teeth extraction, you first need to go to a professional and formal dental hospital or clinic to find a doctor for oral examination, and then take a panoramic film to analyze the difficulty of tooth extraction as well as the shape of the tooth root, etc., to determine the cost of extraction as well as the program and then sign the informed consent form. 2. Extraction surgery: before starting the extraction, the mucous membrane of the operation area will be disinfected, and then local anesthesia will be administered. After the anesthesia takes effect, a separator will be used to bluntly separate the gingiva, and then the affected teeth will be loosened by using a toothpick and the teeth will be removed by using a tooth extraction forceps, and then finally sutures will be applied; for the wisdom teeth that have already been grown out but appear to have a proximal-medial obstruction, a turbine handpiece or ultrasonic bone cutter will be used to grind out resistance before being loosened after anesthesia is administered to prevent damage to the neighboring teeth. damage to neighboring teeth. 3. Post-operative care: After confirming that the crown and roots are completely extracted, the wound will be sutured to help stop bleeding and promote wound healing, and avoid brushing and rinsing for 24 hours, and try not to eat foods that are too hot and too hard for 2-3 days after the surgery. The general process of wisdom teeth extraction is as described above, but there may be some differences in individual tooth conditions and the surgeon’s operating habits.
