What Is the Effect of Timing of Removal on the Incidence and Severity of Complications?

Studies indicate that as one becomes older, third molars (M3s) become more difficult to remove, may take longer to remove, and may result in an increased risk for complications associated with removal. The age of 25 years appears in many studies to be a critical time after which complications increase more rapidly. Conversely, there are no studies indicating a decrease in complications with increasing age. It also appears that recovery from complications is more prolonged and is less predictable and less complete with increasing age. As such, many clinicians recommend removal of M3s in patients as young adults. Advocates of M3 retention need to review carefully with their patients the risks of delaying M3 removal with the same degree of emphasis as the risks associated with operative treatment.
