As a rule, there is no significant pain reaction to tooth extraction, but there may be pain if the tooth is extracted during the inflammatory phase.
If there is no acute inflammation in the periodontal area of the tooth, there is no significant pain. Usually, tooth extraction is done during the non-acute inflammatory phase, and basically, anesthesia is injected. If the anesthesia effect is good, there will be no obvious pain reaction.
However, if you need to extract a tooth during the acute inflammation period, due to poor anesthesia effect, so there may be a pain reaction, generally can be tolerated, but it is recommended to avoid extracting a tooth during the inflammation period.
Note that tooth extraction should go to a regular medical institution for treatment, and if the pain is serious, you should consult a doctor in time.
