There are two main methods of anesthesia for outpatient oral surgery; anesthesia that anesthetizes the nerve endings is called local infiltration anesthesia and anesthesia that blocks the nerve trunk is called nerve block anesthesia. When outpatient surgery is performed on the oral cavity, anesthesia is first applied to the operative area. If the surgery is long, traumatic, and the number of unpredictable intraoperative circumstances is high, local infiltration cannot be achieved and nerve block anesthesia must be performed. Block anesthesia is deeper and lasts longer, typically three to three and a half hours, with better anesthesia.
