The tremendous need for oral surgery has spurred the dental profession across specialties to incorporate surgery into their practices regardless of training and or overall experience.  Fortunately, the vast majority of surgery results in successful dental surgical rehabilitation. However, the incidence of disastrous complications, although rare, have become more commonplace and are now being documented in the literature. The purpose of this lecture is to share with dental professionals and staff, irrespective of their background, the plethora of complications that can occur even in routine surgery. The potential to limit further morbidity may be dependent on early and interceptive diagnoses and surgical management.  The goal of this lecture is to increase the clinician's knowledge and awareness of the broad spectrum of complications.
