I’m Interested in Nitrous Oxide Sedation; Will It Put Me to Sleep?

May 3, 2025

If you’re nervous about your upcoming dental visit, you’re not alone—many patients these days suffer from dental-related anxiety, to the point that they put off much-needed dental care. That’s why many practices these days offer nitrous oxide sedation. Commonly known as laughing gas, this option helps patients feel more relaxed during treatment; however, if you’ve never experienced this sensation before, you may be wondering if it’ll actually put you to sleep. Here’s what you can expect and why it’s a great option for easing dental anxiety while keeping you awake!

How Does Nitrous Oxide Sedation Work?

Nitrous oxide is a colorless, odorless gas that’s mixed with oxygen and delivered through a small mask placed over your nose. Once you start breathing it in, you’ll begin to feel its calming effects within just a few minutes. Most patients describe feeling light, relaxed, slightly warm, and sometimes even a little giggly, hence the nickname; however, you won’t begin laughing uncontrollably.

It’s important to know that nitrous oxide doesn’t actually put you to sleep. You’ll remain fully awake, aware, and able to respond to your dentist throughout the procedure. It simply helps to reduce feelings of fear, anxiety, or discomfort so that you can stay at ease from start to finish. It’s also great for lengthy or particularly complex procedures.

Who Can Benefit from Nitrous Oxide?

Nitrous oxide is a great option for both adults and children who feel anxious about dental care. Your dentist will evaluate your medical history to ensure nitrous oxide is a safe and suitable option for you. In any case, it’s especially helpful for patients who:

  • Experience dental fear or phobia, even for routine preventive care.
  • Have a particularly strong gag reflex.
  • Need to undergo longer or more complex procedures.
  • Struggle with sitting still for extended periods.

If the idea of going to the dentist makes you nervous, don’t let fear keep you from getting the care you need. Nitrous oxide offers a safe, gentle way to take the edge off and make your visit more comfortable. Plus, you’ll be awake and in control the entire time—just calmer and far more at ease!
