I recently had a tooth extraction on tooth #31. ...I developed a blood clot that currently has a whitish in color appearance. ...Isn't a dry socket a painful condition caused when you lose your blood clot....
After tooth extraction, itâs important for a blood clot to form to stop the bleeding and begin the healing process. Thatâs why we ask you to bite on a gauze pad for 30-45 minutes after the appointment. If the bleeding or oozing still persists, place another gauze pad and bite firmly for another 30 minutes. You may have to do this several times.
