In general, the pain caused by tooth extraction will disappear in about 7 days if there are no special circumstances. After tooth extraction, both bone and soft tissues will be damaged to different degrees, and the metabolic products caused by the trauma will stimulate the nerve endings and cause pain, which is a normal postoperative reaction, and this pain has no obvious effect on diet and speech, etc. In most cases, the pain will be gradually relieved in 3-4 days and basically disappear in about 1 week. If the tooth extraction incision is large or the pain is more obvious, consider taking oral anti-inflammatory drugs and painkillers to help relieve the pain. In addition, if severe pain occurs 2-3 days after tooth extraction and radiates to the top of the head, ear-temporal and jaw area with putrid odor, consider the possibility of dry socket and need to promptly seek medical attention for debridement treatment. It is recommended that after tooth extraction, cold compresses can be applied intermittently for 24 hours and antibiotics can be taken prophylactically to reduce the pain and swelling reaction of the wound and prevent infection of the wound.
