There is no need to extract a tooth immediately for inflammation of the tooth, which can be caused by a number of reasons. In case of periapical inflammation or pulpitis, which are common in clinical practice, there is absolutely no need to extract the tooth. As long as systematic treatment is performed for this tooth, a high-speed turbine drill can be applied to open up such an inflamed tooth, then the inflammation in the pulp can be released, systematic root canal treatment can be performed for the pulp, and a crown restoration can be used to protect this tooth, and the inflamed tooth can be made to serve the patient for a longer period of time. There is also the case of pain caused by pericoronitis of the wisdom tooth. Extraction is recommended for inflamed teeth, but it is not recommended to extract during the obvious painful period of inflammation, but rather to treat the tooth symptomatically during the painful period and wait until the tooth is less painful before extracting this tooth.
