Nitrous Oxide Sedation

What is Nitrous Oxide?

Although the thought of undergoing Nitrous Oxide Sedation might scare you, there’s nothing to be nervous about. It’s a common procedure with low risks and many benefits. You may know of Nitrous Oxide by its other name, laughing gas. It is often used by surgeons and dentists due to its effective, yet safe and gentle sedation that helps patients.


If patients experience fear or discomfort while visiting the dentist, sedation can be used to put them completely at ease. It is not used to put patients asleep, but rather dull their senses and allow them to relax. Once the gas is inhaled through the lungs, the relaxing properties take over.

Why People Choose Dental Sedation?

  • Low pain tolerance
  • Anxiety or fear of the dentist or of pain
  • Have a hard time remaining still during dental procedures
  • Have tooth sensitivity that would make the procedure painful
  • Need a lot of dental work in one sitting
  • Have a strong gag reflex that would interfere with treatment

Is Dental Sedation Safe?

You should not be concerned about the safety of Nitrous Oxide since there is a large safety margin when it comes to administering the gas. There are 12 or more features (both visual and audio) that prevent any negative effects from happening while you are under sedation. Certain practices, like system maintenance, good ventilation, and safe work procedures, limit the dangers of being exposed to too much of the gas.

What Should You Expect with Nitrous Oxide?

Now that you are aware of the gas and its uses, it is also important to understand how it is applied and the side effects that may be involved.


To administer the gas, a specialist places a rubber mask over your mouth and nose. The mask is attached to a hose, which is attached to a tank of the laughing gas. The tank may either be portable, on a wheeled stand or fixed into one location.


As you breathe in, you inhale the gas, and the effects will take place within a few minutes; it usually takes between three and five minutes for it to fully kick in. Once it does, you will feel extremely calm and very little will bother you at this time. Most dentists will use a local anesthetic as well as the laughing gas, so the pain is really kept to a minimum. If you’re prone to gagging, the gas will also limit your gag reflex.


While under the effects, you are fully aware of your surroundings but you are less likely to respond to the things that happen around you. You are conscious the whole time but may feel very detached from the actual procedure.


The effects of the gas tend to wear off in a short amount of time after a procedure is completed, usually within 3-5 minutes after treatment. For this reason, you can usually drive yourself home after a procedure with this type of sedation. One of the benefits of Nitrous Oxide is that it is a very mild sedation and you can be fully functioning shortly after a dental procedure, with no major side effects like grogginess. However, for other types of sedation (like oral sedation), you might not be fit to drive after the procedure.
