One of the more common postoperative complication for a tooth extraction is dry Socket. Dry socket can delay the normal healing process and results when the newly formed blood clot in the extraction site does not form correctly or is prematurely lost. This blood clot lays the foundation for new tissue and bone to develop over a two-month healing process. Dry socket can be very painful and you should see a dentist right away if you feel you may have dry socket after a tooth extraction
