Manage Your Child’s Dental Anxiety

Finding a way for kids with dental anxiety to get the care they need without undue stress is a top priority for the team at Iris Pediatric Dentistry. That’s why we provide safe, professionally administered nitrous oxide in-office, making dental visits less stressful for both kids and parents.

While nitrous oxide is an option, it’s never a necessity. However, we find that it often helps children undergoing treatment that requires an injection or a longer procedure. It’s a highly-effective approach for kids who have extreme dental anxiety, a sensitive gag reflex, or are too young to understand the steps in their treatment process.

What is Nitrous Oxide?

Nitrous oxide is an odorless, colorless gas used as a mild sedative in pediatric dentistry. Also known as “laughing gas,” nitrous oxide helps kids relax during their treatments, reducing dental anxiety and helping them get the dental care that they need.

Kids who receive nitrous oxide will remain awake during treatment, but they will be more relaxed and have a reduced gag reflex when working on back teeth. We explain to kids that they will feel floaty, giggly or like they are “walking on clouds”. Nitrous oxide is always mixed with 100% oxygen.

What Happens When a Child Receives Nitrous Oxide?

Before moving forward with treatment, Dr. Murray will discuss your child’s health history with you to ensure nitrous oxide is a good option.


Dr. Murray lets kids see and smell the mask before turning on the laughing gas. Almost all kids smile when they smell the strawberry or orange flavored nose mask, and Dr. Murray lets them relax for a few minutes while they pick a kid’s movie to watch during treatment.

Quick and Efficient

One benefit that makes nitrous oxide such a popular option is that the effects wear off very quickly. After treatment, all children get at least 5 minutes of 100% oxygen to ensure that the nitrous has been exhaled from their system.

Your child’s face may still feel numb if numbing medication was also used, but the relaxation effects of the nitrous oxide will be gone after the mask is removed. Kids can return to school and eat after nitrous oxide.

Further Sedation Options

If your child needs deeper sedation to get through dental treatments, other options are available. Dr. Murray works with the team of pediatric anesthesiologists at Children’s Hospital Colorado to help kids rest comfortably throughout dental treatment.

The Cost of Nitrous Oxide Treatment in Denver

The cost of nitrous oxide treatment for your child will vary depending on your insurance coverage. The good news is that many insurance plans fully cover this procedure! If your family is covered by Colorado Medicaid, the cost is $0. Without insurance, you can expect to pay $1000 – $1500 or more. Iris Pediatric charges an $80 fee for nitrous treatment.

If you suspect that your child may require nitrous oxide treatment during their next dental visit, we suggest contacting your insurance provider to get a quote before visiting our pediatric clinic in Denver.

Frequently Asked Questions

Rest assured, Nitrous oxide is an extremely safe option for your child when administered under the care of a doctor. Most children only experience mild drowsiness after treatment. However, it’s possible that your child may experience side effects from their nitrous oxide treatment. The most common side effects are agitation, headache, and nausea.

Kids who receive nitrous oxide will remain awake during treatment, but they will be more relaxed and have a reduced gag reflex when working on back teeth. We explain to kids that they will feel floaty, giggly or like they are “walking on clouds”. Nitrous oxide is always mixed with 100% oxygen.

Only a few minutes! Once the nitrous laughing gas is turned off the child will breathe 100% oxygen for 5 minutes to ensure the nitrous is flushed from their lungs. The child’s face may still be asleep if an anesthetic was needed for the procedure, but the laughing gas will have no residual effects. The child can go back to school, playing or activities as they choose that same day.

Stan Volman

I took my two-year-old daughter for her first-time visit to a dentist. The facility looked amazing and very kid-friendly. The staff is so professional dealing with children, I was very impressed. Dr. Leslie took her time to convince my daughter that everything would be just great. I am completely satisfied with our new kid dentist. Thank you very much. See you in six months.

Gabriela Maldonado Bell

My 3 & 5 yr olds love their visits to the dentist. Dr. Leslie and her hygienist Wanda are both so kind and respectful of their curious little patients. We’re a bilingual family and the fact that the staff speaks Spanish goes a long way to helping my kids feel comfortable. Couldn’t recommend them enough!

Samantha Alarcon

Dr. Murray and her staff were all so kind and engaging to my two-year-old during her routine exam. They let her get to know her surroundings and touch the dental instruments before having her teeth brushed, and Dr. Murray was very informative about methods to keep her teeth healthy. It was our first time visiting, but definitely the best dental visit I've had with my toddler!
