Benefits of Nitrous Oxide Sedation

Nitrous oxide, often called “laughing gas,” is a safe and effective sedative agent that is mixed with oxygen and inhaled through a small mask that fits over your nose. Benefits include

Rapid Anxiety Relief

It helps patients of all ages feel calm and relaxed within minutes of starting the flow.

Pain Reduction

It increases your comfort level during procedures, making local numbing more effective and less noticeable.

No "Hangover" Effect

The gas wears off almost immediately once the mask is removed, meaning you can drive yourself home or return to school/work right after your appointment.

Suppressed Gag Reflex

It is highly effective for patients with a sensitive gag reflex, allowing the dentist to work more efficiently.

Time Flies

For many patients, nitrous oxide creates a sense of “time compression,” making longer appointments feel like they passed in just a few minutes.

What makes a good candidate?

You or your family member might be a good candidate for nitrous oxide sedation if you:

  • Experience dental anxiety or fear

  • Have a strong gag reflex

  • Are a child who is nervous

  • Have sensitive teeth

  • Need to undergo multiple treatments

  • Prefer a sedation option that wears off immediately


At Smilee Dental, we evaluate each patient’s medical history to ensure nitrous oxide is the safest and most effective choice for your comfort.

Step by Step Process

Your Nitrous Oxide Sedation, Step by Step

Consultation and Health Review

We begin with a brief review of your medical history and dental goals. Dr. Lee will explain how nitrous oxide works and ensure it is the safest, most effective option to help you or your child feel completely at ease.

Personalized Comfort Plan

Every patient’s level of anxiety is different. We tailor the sedation flow to your specific needs, ensuring you receive just the right amount of relaxation to make your procedure—whether a cleaning or a filling—a positive experience.

Gentle Administration

You’ll breathe a sweet-smelling blend of nitrous oxide and oxygen through a small, comfortable mask over your nose. Within minutes, a warm, “floating” sensation will set in, and any dental fears will begin to melt away.

Relaxed Dental Care

While you remain fully awake and able to communicate with our team, Dr. Lee performs your dental work. The sedation helps the time pass quickly and keeps you calm and comfortable throughout the entire process.

Rapid Recovery and Follow-Up

Once the treatment is complete, we switch to pure oxygen for a few minutes. The effects wear off almost instantly, leaving you feeling alert and ready to drive or head back to school with a healthy, happy smile.

What Our Patients Say About Us

"Best experience ever"

First timers at this kid dental center best experience ever having a kid that hates the dentist and she did awesome she felt comfortable. Staff here is super friendly Pricilla and Dr Lee made us feel welcomed and comfortable throughout the whole process. They explained the whole process which I love communicating and knowing what’s going on. I recommend this location to everyone with kids.

"Amazing staff and amazing strategies"

Amazing staff and amazing strategies to make kids willing to do the work on their teeth. My son tried 2 different places and he would not open his mouth to fix his cavities but here 3 amazing staff members were able to make him comfortable and fix 5 cavities at once. I’m very happy that he got his feeling finally done.

Frequently Asked Questions

Still have a question?

Is nitrous oxide safe for children?

Yes! It is one of the safest forms of sedation in dentistry. It is non-addictive, and the patient remains fully awake and able to respond to the dentist throughout the visit.

Most patients experience a pleasant, “floating” sensation or a feeling of tingling in the arms and legs. Some people get the “giggles,” which is why it’s called laughing gas!

While you don’t need to fast completely, we recommend a light meal a few hours before your visit to prevent any potential nausea.

Once we turn off the gas and provide pure oxygen for a few minutes, the effects disappear completely. You will feel totally back to normal before you leave the office.

Nitrous oxide has very few side effects. Occasionally, a patient may experience slight nausea if they have a very full stomach, which is why we recommend a light meal beforehand.
