Is Nitrous Oxide Safe at The Dentist? 

added on: October 17, 2022

Your dentist in Greenwood Village strives to make every dental appointment fun and stress-free for all of our patients. But we do understand that some of our patients may be nervous, anxious, or scared of their visit. While we will certainly use all our techniques to help you relax, there are some times when we need to consider using a form of sedation dentistry such as nitrous oxide. But what is nitrous oxide? Is it safe? Don’t worry, we are here to help answer your questions. 

What is Nitrous Oxide?

Nitrous oxide is a gas that has no smell and no color but can help relax patients while in the dental chair. It simply helps soothe the mind and makes getting dental care easier, more comfortable, and more enjoyable. This is important, especially for kids, because a kid’s experience with a dentist in their earlier years can affect their attitude about dentistry throughout their life. In fact, a study published in the National Library of Medicine found that many adults who are scared of the dentist can trace their fear back to a negative experience that occurred during childhood, and those adults are less likely to have regular dental and more likely to have dental problems. 

Is Nitrous Oxide Safe? 

Yes! The American Dental Association considers nitrous oxide safe for patients to use during their dental appointments with proper moderation. Now, it shouldn’t necessarily be used on every patient in every situation, but it can be beneficial for patients who:

  • Will be having a longer procedure
  • Have trouble sitting still 
  • Have a strong gag reflex
  • Experience fear
  • Are special needs patients 

If your dentist in Greenwood Village recommends nitrous oxide for you, know that it is safe and the effects wear off quickly. 

How Is Nitrous Oxide Administered?

One of the great things about nitrous oxide is that there are no needles involved, and it can be administered directly through a small nose mask. This mask only covers your nose and delivers nitrous oxide, along with oxygen, simply through breathing. It takes about five minutes for the nitrous oxide to take effect. After treatment is done, you will breathe just oxygen for a little bit to clean out any gas and will have no lingering drowsiness from the nitrous oxide. Sometimes, nitrous oxide can cause nausea so we may encourage only a small meal or snack before any nitrous appointment. 

If you need dental treatment that may take a while or if you’re scared of the dentist, talk with your dentist in Greenwood Village about how we can help. We’re always accepting new patients and would be happy to help!
