Nitrous oxide, commonly known as laughing gas, is a widely employed approach to alleviate mild to moderate anxiety. Delivered via a compact mask placed over the nose, it proves to be an efficient means of soothing anxiety, increasing one’s tolerance for pain, and creating a perception of time passing more swiftly. Once the gas takes effect, a sense of calmness ensues, allowing the individual to remain awake and engaged in conversation with the dentist.

Upon the conclusion of the appointment, normal breathing with oxygen is resumed, causing the effects of nitrous oxide to dissipate entirely. This enables individuals to promptly resume their usual activities without any lingering impact.
