Nitrous oxide, also known as laughing gas, is a very safe form of sedation that is used in many dental practices. The gas is mixed with oxygen and delivered to the patient through a mask placed over the nose. The patient will feel relaxed, but not unconscious, and the effects wear off quickly. If you would like to know more about how Dr. Everett Eklund uses laughing gas at Potomac Dental Centre in Hagerstown, Maryland, or to plan your next appointment, call 240-329-2398
