Toothache while sleeping after tooth extraction may be caused by the disappearance of anesthesia drugs, large incision, psychological effects, etc., as follows.
1. Anesthesia drug effect disappears: anesthesia drugs have a certain anesthesia maintenance time, lidocaine is generally 1.5~2 hours, ativan is generally 2.4 hours, bupivacaine is generally 6 hours, ropivacaine is generally 9 hours. When the effect of anesthesia drug disappears, pain symptoms may appear.
2. Larger incision: For larger traumatic extraction wounds, such as flap bone removal, the blood clot is easy to fall off, the alveolar bone wall of the nerve endings are exposed, and the stimulation causes pain.
3. Psychological effect: sleep is more concentrated, this time the feeling of pain is more sensitive.
If the pain symptoms are serious and continue to be unrelieved, it is recommended to go to the hospital in time to receive professional treatment as soon as possible.
