Before general anesthesia can be administered it is important to have bloodwork, x-rays, and an ECG done. It is also important to monitor breathing, heart rate and other vital signs. General anesthesia under dentistry is usually suggested for patients who are required to undergo complex dental procedures like wisdom tooth extraction or those who have extreme anxiety. It is also recommended for patients who have a high tolerance for other sedation like Nitrous oxide, Oral conscious solution and IV sedation.
