What Is Nitrous Oxide Sedation?

Feb 2

Nitrous oxide, sometimes known as "happy gas" or "laughing gas," is a gas. Giving nitrous gas to a kid during dental treatment might make them feel less discomfort and anxious. Your youngster will be awake throughout the surgery since the gas is administered through a little nosepiece. After their dental procedure has been done, children normally recover quickly from the effects of the gas.

Prior to the operation

You must offer your agreement to employ sedation and consent for the dental operation as the parent or caregiver. You should be aware of the following dangers and causes for sedation:

  • Oxygen levels in your youngster may decline in some circumstances. They will be provided oxygen via an oxygen mask if this happens. Throughout the operation, nurses will keep an eye on your child's respiration.
  • It's possible that some kids will puke. They may, on rare occasions, inhale vomit, necessitating medical attention.


Two hours before the treatment, your kid can have a light meal and drink, such as jelly, soup, or toast. They should not eat or drink anything after that until the surgery is completed.

Nitrous oxide sedation in the dental chair is used during the process. The sedative gas will be inhaled through a little nosepiece that will be placed on your child's nose. Their mouth isn't covered.

  • Nitrous oxide induces drowsiness and relaxation in youngsters. Your child will still be aware of their surroundings, but will feel dreamy and floating, warm, and tingly in their hands and feet. They could be a bit forgetful and forget the operation afterwards.
  • Staff will check your child's degree of drowsiness while administering the nitrous oxide to ensure that they can still comply and follow spoken commands.
  • It will be carried out the dental treatment. To ensure that your kid is pain-free, local anaesthetic injections may be administered. While your kid is sedated, you can administer these medications.

Following the surgery

After their dental treatment, your youngster will swiftly recover from the effects of the nitrous oxide. Following the sedation, they will be watched for a short time.

Some youngsters may become nauseous or unwell as a result of the procedure. Give your child a glass of water if they are unwell or vomit. If your toddler refuses to drink water, consider clear drinks such diluted fruit juice, icy poles, jelly, or clear soup.

If your kid has also had a local anesthetic, they should avoid biting their lip or cheek while it is numb.

When should you consult a physician?

If your kid vomits more than twice during the first hour of treatment, or if you have any concerns about their recovery, contact your treating dentist.

Recall the following points:
During dental operations, nitrous oxide gas helps a youngster feel less pain and fear.
Before your child is sedated, you must first give your consent.
The effects of nitrous oxide gas sedation on children often wear off fast.
