No, not like general anesthesia, which we do not use. With nitrous oxide, you are relaxed and fully awake. With oral sedation, you are drowsy, may doze, and remember little, but can answer a question. With IV sedation, you are in a deep, dreamlike state, yet you breathe on your own, and your heart rate, blood pressure, and oxygen are monitored throughout.
The level that fits depends on your anxiety, the treatment, and your health history, which Dr. Magid reviews with you first. With oral or IV sedation, someone drives you home; with nitrous oxide, you can drive yourself.
