Does your child feel nervous about visiting the dentist? Dental anxiety is very common among children, especially during new or unfamiliar procedures. This is why laughing gas is available to help patients feel more comfortable. 

Also known as nitrous oxide, this type of sedation dentistry can help make dental visits easier and less stressful. Here’s what you should know about it. 

What is Laughing Gas?

Laughing gas is a mild sedative made from a mixture of nitrous oxide and oxygen. During dental treatments, a small mask is placed over the child’s nose so that they can breathe in the calming gas. Within a few minutes, most children begin to feel relaxed and less anxious. 

Despite its name, laughing gas does not always make patients laugh. Most experience feeling light, calm, and sleepy. The whole goal behind using the gas is to help the child feel at ease during other dental visits. 

Is Laughing Gas Safe for Children?

Laughing gas has been used routinely in pediatric dentistry for many years and is considered one of the safest sedation options for children. The effects are mild, carefully controlled, and wear off quickly once the mask is removed.

At Pediatric Dentistry Kahala, the safety of our patients is our utmost priority. That’s why we monitor your child closely throughout the appointment to ensure they remain safe and comfortable. 

When is Laughing Gas Used?                   

There are many different reasons why laughing gas may be recommended for your child, aside from having dental anxiety or fear. For instance, kids with a strong gag reflex or sensitivities may benefit from the sedation.  

What’s more, when kids have a hard time sitting still or are undergoing longer or more complex procedures, the use of nitrous oxide can make the entire experience more relaxed and efficient. The patient can sit back while the dentist is able to effectively and timely complete the procedure.

Every child is different, and laughing gas is gentle enough to use in many different scenarios. 

How Should Parents Prepare Their Child for Laughing Gas?

As a parent, one of the best ways you can prepare your child for experiencing sedation dentistry in Honolulu at their next dentist appointment is to keep the conversation positive and simple. Use words they are familiar with and avoid words that may sound scary or intimidating. Let your child know that the small mask they are to breathe through will help them feel comfortable.

We want to do everything we can to ensure your child has the best possible experience on their visit.
