After extracting the tooth and taking painkillers it is still very painful. At this point the problem should be analyzed specifically. First of all, you should check how long after the extraction of the tooth, if it is just after the extraction of the tooth, the pain is more intense. After eating painkillers pain slightly relieved, but there is still pain, this situation we generally believe that is normal, because in the period of time just after the extraction of teeth, relatively speaking, there will be obvious swelling and pain. The pain medication, a large part of the pain relief symptoms, but did not achieve the effect of completely make the pain area 1 point does not hurt, so this situation is considered normal, and pain medication has a certain effect. However, if the tooth has been removed for more than 3 days and there is still severe pain in the wound area, and pain medication is not effective, then attention must be paid to the possibility of post-extraction infection or post-extraction dry socket. In both cases, it is necessary to go back to the dentist as soon as possible to treat the symptoms.
