Conscious sedation is a type of sedation in which the sedated individual can respond to verbal directions, but he or she feels little to no pain, and has an altered level of consciousness. This level of sedation is used for medical procedures in which it is necessary for the patient to be responsive, and also for minor procedures which do not merit the use of general anesthesia, and for procedures involving patients who cannot cooperate with care providers.
During nitrous oxide conscious sedation (laughing Gas), you will remain awake but in a sedated state so your dental anxiety and phobia will be diminished. As a result you will feel much more relaxed and comfortable while undergoing your dental procedure.
Patients receiving sedation dentistry generally need to avoid eating or drinking for 4 hours prior to the appointment.
