Did you know that sources estimate that approximately 36% of people suffer from dental anxiety? Many people get nervous when it comes to oral healthcare visits, whether they need a routine exam or have a more complex procedure to undergo, such as a root canal.

Thankfully, many dentists offer sedatives, such as nitrous oxide, that can help you feel comfortable and calm throughout your appointment. However, you might avoid this medication if you’re unsure whether it’ll ‘knock you out’. If you’re scared that laughing gas will render you unconscious, continue reading to learn why you can safely set your concerns aside.

What is Nitrous Oxide?

Nitrous oxide, or laughing gas, is a medication that’s mixed with oxygen and administered through a breathing mask placed over your nose while your dentist works. The effects kick in within moments of first inhaling the ingredients, and dissipate just as quickly once the mask is removed. This makes it an ideal solution for keeping you comfortable for minor and major procedures, depending on your needs.

This medication interacts with various chemical messengers in your brain to inhibit your sensitivity to external stimuli. Plus, it blocks certain receptors and triggers the release of endorphins, a natural “feel-good” neurotransmitter.

What Does Nitrous Oxide Sedation Feel Like?

Are you worried that laughing gas will have you divulging all your deepest secrets, or that it might put you to sleep? If you’re afraid you’ll lose all inhibitions, you can set your mind at ease.

Everyone responds a little differently, but typically, nitrous oxide doesn’t result in a complete loss of control.  This medication slows down your nervous system, reducing your body’s responses to external sensations. This often induces a deep sense of relaxation or euphoria, and you might feel tingling in your limbs or giggle seemingly inexplicably.

Will Nitrous Oxide Put Me to Sleep?

It’s natural to wonder or worry how you’ll be affected by laughing gas, but fortunately, it’s been used as a sedative since the mid-19th century. That means its effects have been well documented, and it’s generally considered safe for most people when administered by a trained professional.

Nitrous oxide isn’t intended to render you unconscious, like general anesthesia at the hospital does. Instead, you’ll likely feel calm, happy, and potentially a little light-headed. There’s a chance you might feel so relaxed that you naturally doze off while your dentist works, but usually, patients remain awake but at ease while inhaling nitrous oxide.

If you’re still unsure whether laughing gas is right for you, the best way to learn is to consult your dentist directly!
