Laughing gas/Nitrous oxide Norlane Geelong

You don’t have to struggle with dental anxiety. Find out why laughing gas is no joke.

Nitrous oxide is a safe and helpful sedative that is combined with oxygen and inhaled through a mask that fits over your nose to help you stay calm during treatment.

Nitrous oxide, also called “laughing gas”, is one option your dentist may provide to help you relax during some procedures.

It is not intended to put you to sleep. You will be able to hear and respond to any requests or instructions the dentist may have.

Your dentist will have you breathe normally through your nose, and within a few minutes, you should start feeling the effects of nitrous oxide.

You may feel lightheaded or have a tingling in your arms and legs. Many people say their arms and legs feel heavy.

Eventually, you should feel calm. The effects of nitrous oxide wear off soon after the mask is removed.

Consult with your dentist to learn if nitrous oxide would be a good option for you.

Nitrous Oxide for Children

Nitrous oxide is not only safe for children but also a recommended sedation method for children who are anxious or nervous about a dental procedure.

Consult with your child’s dentist to determine the appropriate sedation method to be used. Some children may experience nausea or difficulty wearing the mask needed to breathe it in.

Effects of Nitrous Oxide

Nitrous oxide slows down your body’s responses and your brain, and the specific effects of the drug depend on how much has been inhaled.

Inhaling nitrous oxide causes:

  • feelings of euphoria, relaxation and calmness
  • fits of giggles and laughter – hence the nickname ‘laughing gas’
  • sound distortions and hallucinations

Nitrous Oxide for Dental Procedures

Before the Procedure

Before anything else, you must give your consent to use sedation and consent for dental treatment. You need to understand the reasons for sedation and the following risks included:

In some cases, your oxygen levels may drop. If this happens, you will be given oxygen through an oxygen mask. A dental assistant will carefully check your breathing throughout the procedure.


You can have a light meal, like jelly, soup or toast, and a drink two hours before the procedure. After that, you should have nothing to eat or drink until after the procedure.

During the Procedure

Nitrous oxide is given in the dental chair. You breathe the gas through a small nosepiece that sits on your nose. It does not cover your mouth.

The nitrous oxide makes the patient feel sleepy and relaxed. You will still be aware of what is happening around, but will feel dreamy and floaty, warm, and have tingling of the hands and feet.

You may be a little forgetful, and might not have any memory about the procedure afterwards.

While administering the nitrous oxide, the assistant will monitor your level of sedation to ensure that you can still cooperate and follow verbal instructions.

The dental treatment will be performed, while you are sedated. Local anaesthesia may also be administered so that you will not feel any pain.

After the Procedure

You will recover from the effects of the nitrous oxide very quickly once your dental treatment has been completed. You will be observed for a brief period after the sedation.

Some patients may feel a little sick or nauseated. If you feel sick or vomit, drink plenty of water to stay hydrated.

Be careful not to bite your lip or cheek while it is numb.
