There are several different types of extractions. Routine extractions remove whole teeth that may be crowding other teeth or preventing another tooth from coming in through the gum. If the tooth is decayed or damaged, a complicated extraction may be required to remove it. Wisdom teeth extraction represents a soft tissue impaction where the gum is cut to remove the teeth. Bone impactions also require surgical removal. Pain control can be accomplished with a local anesthetic, nitrous oxide, IV (I-V) sedation, and even general anesthesia. These options can make the procedure nearly painless. New bone and gum tissue will grow over the extraction site in time. To prevent post operative complications, the dentist's or surgeon's directions on cleaning and medicating the area should be followed. Additional information on extractions can be provided by a local dentist or oral surgeon.
