If the pain is still present one week after tooth extraction, it may be considered whether infection has occurred, and some patients may have reactive pain for a longer period of time after surgery due to personal physical reasons. Therefore, if the pain is still present a week after the extraction, it is not obvious and can be observed again. Considering that the pain is more pronounced, it is important to go to the hospital for a review to check for the possibility of local infection. If there is an infection, treat it by fighting the infection. There is also the possibility of dry socket, and it is even more important to go to the hospital for follow-up treatment as early as possible. Therefore, if there is still pain one week after tooth extraction, observation can be performed if it is relatively mild. If the patient feels that the symptoms are more severe or if there is really pain or radiating pain, he can go to the hospital for follow-up and treatment after examination.
