Nitrous oxide is a sweet smelling gas that is breathed through a small mask that covers your nose. It is a form of sedation that is designed to make you more relaxed during your appointment. It is commonly used during shorter dental appointments.
Conscious sedation is a deeper level of sedation than that provided by nitrous oxide analgesia. Conscious sedation provides a calming feeling without the risk of general anesthesia. With conscious sedation, medications are administered orally or though an IV line in the arm that depresses the patient’s level of consciousness. Unlike general anesthesia, patients are able to breathe on their own as well as respond to verbal commands. Generally, a patient sedated with conscious sedation will not remember anything about the procedure.
