Nitrous oxide is also called “laughing gas” (conscious sedation). It is used with young patients or anxious adults who are afraid of dental treatments. This type of sedation allows the patient to be calm, which makes the appointment more pleasant.
Nitrous oxide is administered by inhalation. Nitrous oxide will temporarily block certain receptors in the patient’s brain, which will reduce inhibition. Nitrous oxide increases the effect of anesthesia. It reduces the risk of pain or discomfort during treatment.
After the treatment, oxygen is administered through the nasal mask to remove the effect of the nitrous oxide. It is perfectly safe to drive or go about your business after receiving the gas.
Don’t worry, nitrous oxide will not cause any damage or harm if administered by a professional.
