Many people are extremely nervous about dental procedures even with today's advancements and require additional medications to calm their fears. The most often used technique is nitrous oxide gas, often referred as laughing gas. It helps relax patients by breathing a gas administered through the nose. Some patients need to be calmed before they get to the office. In these instances, they can be helped with an oral medication taken prior to their appointment to relax them. People who are extra anxious and do not benefit from these methods can be best served general anesthesia.
