Conscious sedation using nitrous oxide is widely used in dentistry. The gas works by relaxing the patient but without causing them to lose consciousness, allowing them to react to stimuli. Fear of going to the dentist can be a serious issue. For many people, this can be a significant obstacle, especially those with a fear of the dentist, fear of needles and anesthesia, or any type of anxiety before a dental procedure.

There are several advantages to using nitrous oxide sedation. The effect is
immediate and is entirely controlled by the dentist, who can reverse it at any time (through the inhalation of oxygen). But of all the advantages, the most important one is safety. Nitrous oxide sedation is considered one of the safest sedative procedures in dentistry.
