If you need to drive yourself to and from your appointment, you may receive nitrous oxide without impairment to your safety. This is because nitrous oxide is inhaled rather than ingested. As such, its effects are quickly reversed so you can go about your normal activities after leaving the office. If you want to receive oral conscious sedation for your dental treatment, it will be necessary for you to arrange to have someone accompany you to your appointment who can drive you home. It is wise to take the rest of the day off after receiving oral conscious sedation.
