Do you feel nervous when you go to the dentist? Your dentist may suggest the conscious sedation which is a mixture of oxygen and nitrous oxide.
Nitrous oxide is a gas that is used in combination with pure oxygen and affects your stress level for as long as you breath it. It will calm and reduce the stress level of people with high anxiety when they go to the dentist. The nitrous oxide acts as a relaxant to the brain. Unlike general anesthesia, nitrous oxide allows the patient to stay conscious during the treatment.
