Pulling out your own teeth can be very dangerous and may result in severe pain, infection of the wound after the extraction, and fracture of the root of the tooth. 1. Since there is no anesthesia for self-extraction, the process of self-extraction is often accompanied by severe pain, which can be life-threatening if you have a history of heart disease, high blood pressure, or cardiovascular disease. 2. Because self extraction can not do aseptic operation, and after self extraction can not do timely cleaning of wounds, so it will lead to wound infection, and serious cases will appear systemic symptoms, such as high fever, chills, white blood cell count rise. 3. There is no corresponding instrument for self extraction, and the extracted tooth cannot be guaranteed to be complete, so the root of the tooth will be broken, and the residual root will appear. In conclusion, there is a great risk of pulling out the tooth by yourself, so once you need to pull out the tooth, please go to the local medical institution in time, do not pull out the tooth by yourself.
