All You Want To Know About Nitrous Oxide Sedation

Do you feel anxious about going to the dentist? Does being in the dental chair make you feel uneasy? You’re not alone. One in six Australian adults and about one in ten children have dental anxiety. Dental anxiety stops people from getting the care they need and it can worsen any dental problems. The good thing is there’s a way to make your dental visits much less stressful, and it’s called nitrous oxide.

What is nitrous oxide?

Nitrous oxide (N2O) is a mild sedative to help patients calm down during dental procedures. It is a clear and sweet-smelling gas that induces relaxation for painless dentistry. It’s widely known as ‘laughing gas’ because, in some cases, it can induce feelings of happiness and giggles.

Nitrous oxide is one of the more gentle and safer options for sedation dentistry.

Dentists administer laughing gas through a nosepiece, mixed with oxygen for safety and comfort. It takes just three to five minutes to induce relaxation without making you unconscious. The best part is that dentists can adjust the amount of laughing gas to ensure you experience the right level of relaxation and pain relief. You’re in control, and we follow your guidance.

Nitrous oxide is a great option for mild treatments or moderate dental anxiety because it leaves your system quickly. There’s no recovery period, so you can get back to your regular activities right away.

Benefits of laughing gas

Now that we understand how nitrous oxide works, let’s explore its benefits for anxious patients:

  • Immediate relaxation. Laughing gas takes effect quickly, providing immediate relief from anxiety. It helps you feel calm and comfortable within minutes of inhaling the gas.
  • Customisable dosage. One of the significant advantages of this option is its flexibility. The dentist can adjust the gas dosage to meet the specific needs of each patient, ensuring a personalised and tailored experience.
  • Maintains consciousness. Nitrous oxide allows you to remain conscious during the procedure, which is essential for effective communication with the dentist. You can ask questions or express concerns as needed while being sedated.
  • Rapid recovery. Unlike some other sedation methods, this one has a fast recovery time. Once the gas is turned off, its effects wear off quickly. This allows you to resume your regular activities without lingering drowsiness.

Who can benefit from this sedation option?

Nitrous oxide is suitable for a wide range of patients, including:

  • Kids and adults who feel scared or anxious about going to the dentist.
  • People who find dental procedures painful.
  • Those having long or uncomfortable treatments.
  • Those with a strong gag reflex that can complicate dental work.

How effective is nitrous oxide?

Nitrous oxide is effective at reducing anxiety and creating an overall sense of well-being. Many patients describe the sensation as feeling light-headed or euphoric, hence the nickname ‘laughing gas.’ This relaxed state helps you handle dental treatments that might otherwise seem intimidating.

How safe is it to use laughing gas?

Nitrous oxide is generally considered safe, especially when administered by trained dental professionals. Throughout the procedure, they monitor oxygen levels and adjust gas flow to ensure your safety. After your treatment, your dentist provides you with pure oxygen to flush out the laughing gas from your system. Since its effects wear off quickly, you can safely drive home post-procedure.

Important things to remember

While nitrous oxide is safe, there are a few important things to keep in mind:

  • Medical History: Make sure to tell your dentist about your medical history, especially if you have any breathing problems.
  • Eating Before Your Visit: To avoid feeling sick, it’s a good idea not to eat a big meal right before a dental procedure with nitrous oxide.
  • Allergies and Sensitivities: Inform your dentist if you have any allergies or sensitivities, particularly to medications or gasses. This information helps your dentist ensure your safety during nitrous oxide administration.
  • Age and Pregnancy: Inform your dentist if you are pregnant or very young, as special precautions may be necessary for these groups when using nitrous oxide.
  • Alternative Options: Talk to your dentist about alternative sedation dentistry in case laughing gas isn’t your best bet, such as oral sedation or IV sedation. These options can be discussed to find the best fit for your needs and preferences.
