What is the purpose of nitrous oxide sedation in dental procedures?

Nitrous oxide sedation, often referred to as "laughing gas," is primarily used in dental procedures to reduce patient anxiety and discomfort. This sedative gas creates a state of relaxation, helping patients feel more comfortable and less fearful during treatment. By alleviating anxiety, nitrous oxide facilitates a smoother dental experience, allowing the dentist to perform procedures with fewer interruptions and increased patient cooperation.

While it can have some effects on pain perception, its primary role is not to manage pain directly nor is it intended to enhance recovery time or improve the effectiveness of local anesthetics. Local anesthetics are typically used to block pain sensations, while nitrous oxide complements this by providing a calming effect, thus making the overall experience more pleasant for the patient.
