Nitrous Oxide

Nitrous Oxide Sedation at Westlake Dental Care

Nitrous oxide, commonly known as "laughing gas," is a sweet-smelling, non-irritating, colorless gas used in dentistry to help patients feel calm and at ease. It has been a trusted method of sedation for decades, known for both its safety and effectiveness. During administration, patients receive a carefully controlled mixture of 30%–50% nitrous oxide with 50%–70% oxygen.

Safe and Gentle Sedation

Nitrous oxide allows patients to remain awake, responsive, and in full control of their bodily functions. Some may experience a sense of calm or mild amnesia and may even drift into light sleep during treatment, often with little memory of the procedure afterward.

Benefits of Nitrous Oxide Sedation

Fast-acting — begins working within minutes
No lingering side effects or “hangover” feeling
Safe for the heart and lungs when properly administered

When to Avoid Nitrous Oxide

Chronic obstructive pulmonary disease (COPD)
Emphysema
Multiple sclerosis (MS)
Upper respiratory infections or congestion
Unusual chest or breathing complications

If you’re unsure whether nitrous oxide is right for you, we recommend a brief trial session to help you decide.
