During the procedure itself, your blood vessels may get injured causing some bleeding, or the nerves could also get damaged and so you would feel numb for a while. Finally, if the extraction was forceful, the bone could crack or break under the pressure. These complications are extremely rare, especially with simple extraction procedures.

After the surgery, if the proper instructions were not followed, the wound could get infected causing severe pain, and a foul taste and smell from the infected wound.

It depends on the location of the anesthesia (or the location of the tooth to be pulled). The anesthesia for all the upper teeth, as well as the lower front teeth should last for only 2 or 3 hours. For the lower back teeth, it could be a bit longer, about 6 hours. Some people even report it lasted throughput the night, only letting up the next morning.

For simple extractions, you could go out the next day and live normally. For surgical extractions, a 3 to 5 days rest is needed for the swelling to go down and the pain to subside.

Hard, hot and spicy foods, disturbing the wound with the fingers or tongue, smoking, and using mouth rinse (water included) for a couple of days.

Antibiotics are rarely needed after tooth extraction. Only cases of severe infection require antibiotics, as prescribed by your dentist.

You should start the rinses 2 days after the procedure. 3 to 5 times a day for 5 days should be sufficient
