There are different levels of sedation to accommodate every patient. Minimal sedation involves inhaling nitrous oxide (“laughing gas”). Nitrous oxide helps you relax and wears off quickly. Electronic anesthesia is an alternative form of mild sedation that uses electronic impulses to help you relax. Conscious sedation is a moderate level of sedation that causes drowsiness and is taken in pill form. IV deep sedation is typically administered intravenously and works very quickly. With IV deep sedation, most patients fall asleep but can be easily awakened. Total sedation could be the only solution for people with an intense fear or phobia of dentistry. With total sedation, or general anesthesia, you are completely unconscious and cannot be easily awakened.
