Does nitrous oxide work? What is nitrous oxide? Nitrous oxide, also known as N2 O, laughing gas, or happy gas, was found and used by a scientist named Joseph Priestly in 1793. It has been used for more than 150 years to relax patients during their visits to the dentist. It is recommended for young children and adult patients with a fear of the dentist or low pain tolerance. Does nitrous oxide work? The short answer is yes! If you or your child have anxiety about or experience pain when visiting the dentist, nitrous oxide may be a solution. If you’re also squeamish around needles, you’re in luck because it is not delivered by giving a shot. It is administered by placing a mask over your nose and mouth and breathing in the nitrous oxide and oxygen combination that comes through the tube. After the procedure, the patient will receive 100% oxygen through the mask to prevent side effects from the nitrous oxide, such as nausea, fatigue, and headaches, and to clear the euphoric effects. What does nitrous oxide do? Contrary to one of its names, laughing gas doesn’t always make patients laugh. Patients may experience feelings of euphoria or carefreeness. They may feel as if they are floating or have a warm, tingling sensation in their body, especially in their arms or legs. They may also feel sleepy or have trouble keeping their eyes open. Unlike other forms of sedation, patients can safely drive and eat after the procedure.
