Extraction is not recommended in most cases of tooth pain, because most of the time the tooth pain indicates an acute inflammatory period, when the extraction of the tooth may cause other risks. On the other hand, toothache is far from being an indication for tooth extraction, as most of the diseases that cause toothache clinically do not require tooth extraction, for example, common dental diseases such as pulpitis and periapical inflammation can be better treated by means of pulpal drainage and root canal treatment, and the tooth can be restored by means of crown restoration, so that the tooth can function normally in our mouth again. It is not necessary to remove the tooth to serve our chewing function. Even for wisdom tooth pericoronitis, although the tooth needs to be extracted, it is extracted during the period when it is not painful, because the extraction of wisdom tooth during the period of pain may cause the spread of infection foci, and in serious cases, may cause bacteremia or even sepsis, so in general, we do not extract the tooth during the period of pain.
