Nitrous oxide metabolizes very quickly and will leave the body within just a few minutes of removing the gas mask. Since nitrous oxide doesn’t linger in the body, it doesn’t cause hangover effects and you will be allowed to return to your normal activities right away, including driving.
Oral conscious sedation on the other hand is a deeper form of sedation that is more intense and lasts for much longer. Most people feel groggy and tired after their appointment for a few more hours. You may feel the effects for up to 6 hours after your appointment but even if you feel completely fine, this sedative can cause lingering hangover effects for up to 24 hours.
This is why you cannot drive, drink alcohol, sign legal documents, or engage in strenuous activity for the next 24 hours. You may be monitored for a little bit after your appointment before we clear you to leave. You will need a chaperone to watch you for the rest of the day and help you get around. We recommend you get some rest when you get home.
