How is his administration going?

The MEOPA is administered by inhalation using a mask that is suitable for the patient's face and age. Within a few minutes, the patient experiences a sensation of relaxation and a decrease in pain, allowing dental care to be performed without the feeling of pain or anxiety. As soon as the mask is removed, the effects of the gas fade within a few minutes, enabling the patient to resume their activities.
