Everyone Says that Nitrous Oxide Is a Total Gas, but Is It Safe?

Dental anxiety is a common problem that prevents many people from receiving the oral healthcare they need to maintain a beautiful smile for life, and sedation dentistry can be an excellent way to make a checkup easier and more pleasant for many patients. Nitrous oxide is one of the most popular sedation methods, and it is amazingly safe for almost everyone. Here’s a quick look at how nitrous oxide works and who it can help.

What Is Nitrous Oxide?

Nitrous oxide, also called laughing gas, is a colorless gas that may taste slightly sweet when you are receiving it, and it can safely make a person less sensitive to pain during a dental procedure. While this treatment may be most commonly associated with dental fillings, it can also be used to help patients who:

  • Have dental anxiety or phobias
  • Have strong gag reflexes
  • Have trouble sitting still in the dentist’s chair
  • Are scheduled for especially long or intensive dental treatments

The patient will start feeling the numbing and calming effects of nitrous oxide within minutes after they begin receiving it. Most people report experiencing feelings of lightheadedness and wellbeing during the treatment.

How Safe Is Nitrous Oxide?

Dentists have used nitrous oxide to help patients remain calm and comfortable during treatment for almost two hundred years, and researchers have found no evidence of long-term side effects in this lengthy span of time. Nitrous oxide is eliminated from the body several minutes after the treatment ends, and short-term side effects such as dizziness or queasiness should fade away just as quickly. This means patients can expect to be able to drive themselves home or back to work after their appointments.

However, nitrous oxide is not for everyone. Issues that may complicate the treatment include:

  • Nasal congestion that blocks the flow of gas to the lungs
  • Previous problems with substance abuse
  • Vitamin B12 deficiency
  • Severe psychiatric conditions

Your dentist and their team will carefully monitor your vital signs while you are sedated to ensure your safety.

Does Nitrous Oxide Make You Behave Strangely?

Despite comedic portrayals on TV and in movies, nitrous oxide will not make you hallucinate, tell secrets, or behave in ways that you would not normally. Most patients receiving the treatment will simply sit peacefully through their dental appointments while remaining able to answer questions and respond to instructions. In the unlikely event that you do say something silly or unseemly during treatment, the dental team will never discuss it afterward.

Nitrous oxide can be a safe and effective way to make dental care easier. Consulting with your dentist can help you find the best type of sedation for you.
