Nitrous oxide, commonly known as “laughing gas,” is a safe and mild sedative used in dentistry to alleviate anxiety and discomfort during dental procedures. Administered through a comfortable mask placed over the nose, nitrous oxide induces a feeling of relaxation and euphoria while allowing patients to remain fully conscious and responsive. It helps patients overcome dental fears and phobias, reduces sensitivity to pain, and creates a calming effect that enhances their overall comfort. Nitrous oxide is fast-acting and wears off quickly, enabling patients to resume normal activities after the procedure without lingering effects. This makes it an ideal option for creating a more pleasant and positive dental experience, particularly for those with anxiety or sensitivity concerns.
