The gas is mixed with oxygen and inhaled. After breathing normally for a few minutes, the patient should feel the effects of the anesthesia. The nitrous slows down your nervous system, resulting in a reduction in inhibition, as well as a light-headed feeling and a heaviness in the arms and legs. The end result is a reduction in anxiety and a general feeling of calmness. One of the key aspects of its use is that the effects resolve after breathing pure oxygen for a few minutes, allowing patients to recover and drive themselves to and from the procedure. If you have anxiety about dental procedures, consider nitrous oxide dental sedation at your next appointment.
