Nitrous oxide is often used as a conscious sedative during a dental visit at our office. The gas is administered with a mixture of oxygen and has a calming and analgesic effect that helps anxious patients relax during their dental treatrnent. Because it is a mild sedative, patients are still conscious and can talk to their pediatric dentist during their visit. After treatment, the nitrous is turned off and oxygen is administered to help flush any remaining gas. The effects wear off almost immediately. Nitrous oxide rarely has side effects. Our pediatric dentists will provide you with pre and post-sedation instructions.
