A Safe Sedation Option for Mild Anxiety and Routine Care
Nitrous oxide is ideal for patients with mild to moderate dental anxiety, low pain tolerance, a sensitive gag reflex, or those who want help staying calm during cleanings or restorative work. It’s also commonly used for children or teens receiving dental care.
Since the effects wear off quickly, it’s a convenient option for patients who want to return to their normal routine right after their visit.
