The duration of pain after tooth extraction usually lasts about 24 hours. In the case of very complex teeth or obstructed wisdom teeth, a hammer is used to widen the socket during the extraction, which can increase the pain time and cause swelling in the jaw and face. In the case of obstructed wisdom teeth, the gum flap is also cut for the flap-over procedure, which also increases the pain. Therefore, the duration of pain after tooth extraction is usually determined by the complexity of the extraction and the location of the tooth. Normally, 24 hours is the soft tissue healing period, and the pain will gradually disappear after 24 hours, but the healing in the whole extraction socket is just starting, so do not use the affected side for chewing.
