There are multiple reasons for a tooth extraction, such as if the tooth is too decayed, if there is an infection, or even if the tooth was damaged, fractured, or broken. When having the tooth or teeth removed, the dentists numbs the area. Although this happens before any extraction, there is still expected to be discomfort during and pain afterwards. Depending on why the extraction was needed, this will have a direct effect on how the dentist has to extract and how long it takes. This can take the pain from just a few days to maybe even a week or so before completely gone.
