The whole process of tooth extraction is mainly divided into several steps such as preoperative, intraoperative and postoperative. The specific operation should be carried out by professional doctors, please do not do it by yourself. 1. Preoperative: Before extracting the tooth, the doctor needs to examine the oral cavity, take X-ray panoramic film to check the growth pattern of the tooth root, determine the difficulty and possible risks of tooth extraction, and determine the extraction plan. 2. Intraoperative: After determining the extraction plan, the extraction area needs to be disinfected and anesthetized with local infiltration, the gingival separator is used to separate the gingiva, and then the tooth is loosened with a toothpick, the tooth is removed with an extraction forceps, and then the alveolar fossa is scraped and then reset and sutured. 3. Postoperative: After tooth extraction, we need to pay attention to the wound treatment, we need to bite the cotton roll for 30 to 40 minutes and then spit it out so as to achieve the purpose of stopping bleeding, and we need to pay attention to the postoperative period of 24 hours, do not eat food with high temperature, it is best to take fluids or semi-fluids as the main, to prevent bleeding of the extraction wound.
