After the tooth is extracted, if the symptoms of pain keep appearing and are not relieved, you must go to the hospital for an examination to see if dry socket or gum laceration has occurred. If not, the main treatment is symptomatic, and you can take anti-inflammatory drugs, such as cephalosporin and ornidazole, which are good for the healing of the extracted tooth and can prevent the occurrence of infection. In addition, if the pain is severe, you can take ibuprofen painkillers for pain relief. However, if a dry socket occurs, go to the hospital for a thorough debridement procedure. For patients who have gum lacerations and have been experiencing pain after tooth extraction, stitches are needed to close the gum lacerations. The stitches are usually removed 7 days after the suturing, and the pain can be basically absent after the stitches are removed.
