It is not possible to extract a tooth yourself. Even teeth that are particularly loose from periodontitis or loose baby teeth in children are not recommended to be extracted by yourself. Although tooth extraction is a common minor outpatient procedure, it involves sterilization and disinfection. The oral cavity itself is a bacterial environment, so routine sterilization is required when extracting a tooth, including sterilization of the surgical area, sterilization of the environment, and sterility of instruments to avoid postoperative infections to the greatest extent possible, and it is difficult to meet these requirements when extracting a tooth yourself. Moreover, tooth extraction may also cause many complications, such as gum fracture, bleeding, hematoma, inflammation, infection after tooth extraction, local nerve numbness, nerve damage after tooth extraction, etc. These are the complications of tooth extraction, any of which will bring great pain to the patient, and extracting the tooth by yourself will increase the probability of these complications. So if a tooth is extracted, it is recommended to go to a specialized hospital for treatment. After the tooth is extracted, you need to wait for two hours before you can eat, and the food should be based on a semi-fluid and liquid diet. If the patient experiences any discomfort, it is recommended to seek immediate medical attention.
