Nitrous oxide, more commonly known as “laughing gas,” is often used as a conscious sedative during a dental visit. The gas is administered with a mixture of oxygen and has a calming effect that helps scared or anxious patients relax during their dental visits. Because it is only a mild sedative, patients are still conscious and can talk to their dentist during their visit. After treatment, the nitrous is turned off and oxygen is administered for 5 minutes to help flush any remaining gas. The effects wear off almost immediately. Nitrous oxide rarely has negative side effects, although some patients may experience minor nausea.
