Is laughing gas safe for children at the dentist?
Laughing gas, nitrous oxide mixed with oxygen, is a well-established way to ease anxiety in children during dental treatment, according to the American Academy of Pediatric Dentistry. The child breathes it through a small nose mask, stays awake and can talk, and the effect wears off within minutes once oxygen is given. At Creative Arts in Dubai it is offered after a medical-history review, and suitability is decided for each child.

What does laughing gas feel like for a child?
Children usually describe it in simple terms: their hands and feet feel tingly or heavy, their body feels warm and floaty, and things seem a bit funny or far away. Some giggle, which is where the name comes from; many simply go quiet and calm. They stay awake, can hear the dentist, answer questions and follow instructions such as 'open wide'.
The gas does not put a child to sleep and does not numb the tooth. If a filling or extraction needs numbing, local anaesthetic is still given, and laughing gas mainly makes that step and the rest of the visit easier to cope with. Some children remember the visit less clearly afterwards, but they are not unconscious.
Explaining it beforehand helps. Many dentists call the mask a 'space nose' or 'magic air' and let the child hold it and smell the flavour before it goes on. Words like 'gas' and 'sleep' are best left to the dentist, who will use child-friendly language.
How is laughing gas given to a child, and how is it monitored?
A typical sequence. Details vary with the child and the treatment.
| Stage | What happens | What parents should know |
|---|---|---|
| Before the day | Your child's health, medicines and breathing are reviewed, and the dentist decides whether laughing gas suits them | Mention colds, blocked nose, asthma, ear or eye surgery and any long-term condition |
| Eating beforehand | Fasting is not required, but a light meal is usually suggested rather than a heavy one | Follow the specific instructions you are given for your child |
| Starting | A small, soft mask rests on the nose; the child breathes oxygen first, then the gas is added gradually | Your child must be able to breathe through the nose for it to work |
| During treatment | The level is adjusted to keep the child relaxed but responsive, while their breathing, colour and responsiveness are watched | Given and monitored by an appropriately qualified, licensed clinician |
| Finishing | The gas is turned off and the child breathes pure oxygen for at least five minutes | Most of the effect clears within minutes |
| Before going home | The clinician checks your child is alert and steady | Plan a quiet rest of the day; follow any advice about the treated tooth |
Recommendations on fasting, monitoring and oxygen at the end are drawn from the American Academy of Pediatric Dentistry's guidance on nitrous oxide for children.
Which children is laughing gas suitable for?
Laughing gas tends to work best for children who are mildly to moderately anxious but willing to cooperate: they will sit in the chair and accept the mask, but they are tense, gag easily or find a longer appointment tiring. It can also help children who struggle with the injection, because it can be started before the local anaesthetic.
It depends on the child accepting the nose mask and breathing through the nose. A child who is crying uncontrollably, refuses the mask or keeps breathing through the mouth will not get much benefit, and forcing the mask on is not the answer. For these children, gentle familiarisation visits, splitting treatment into shorter appointments or, for a small number, a deeper option may be discussed instead. Our guide for parents of a child scared of the dentist covers the non-medical side.
There is no single age at which laughing gas becomes suitable; what matters is whether your child can understand simple instructions and tolerate the mask. At Creative Arts this is judged for each child at the consultation.
When laughing gas may not suit your child, or needs checking first
A blocked nose from a cold, allergies or enlarged adenoids that stop nasal breathing; significant lung disease; an untreated vitamin B12 deficiency; recent ear or eye surgery; or a child who cannot or will not wear the mask. Tell the dentist about all medicines and conditions. If your child has a cold on the day, the appointment may be moved rather than going ahead without the gas working well.
Laughing gas or something else for your child?
Most children need no sedation at all. These are the broad options, from lightest to deepest, as they are usually discussed with parents.
| Approach | Child is | Usually considered when | Recovery |
|---|---|---|---|
| Behaviour guidance only (tell-show-do, short visits) | Fully awake | Most children, including many nervous ones | None needed |
| Laughing gas with local anaesthetic | Awake, relaxed and able to talk | Mild to moderate anxiety in a child who accepts the nose mask | Minutes, after breathing oxygen |
| Deeper sedation | Drowsy; monitoring is more involved | Selected children for whom laughing gas is not enough, after medical review | Longer; the child goes home with an adult and rests |
| General anaesthesia | Fully asleep | Selected children with extensive treatment needs, severe anxiety or some additional needs | Longer; given and monitored by an anaesthesiologist, with fasting rules |
Any option is chosen for the child and the procedure after a medical-history review. Our guide to choosing between dental sedation options compares them in more detail.
Is laughing gas safe for children?
The American Academy of Pediatric Dentistry describes the judicious use of nitrous oxide and oxygen as a safe and effective way of controlling anxiety in children, adolescents and people with special health care needs, provided the child is assessed first and the gas is given and monitored properly. Dental inhalation equipment delivers oxygen together with the gas, the level is adjusted throughout, and the effect fades quickly because the gas leaves the body through the lungs.
Side effects are usually mild. According to the AAPD guidance, the most common are nausea and vomiting, reported in 0.5 to 1.2% of patients, and a heavy meal beforehand makes them more likely. Some children feel briefly dizzy, tired or a little emotional afterwards. Tell the clinician straight away if your child seems uncomfortable during the visit; the level can be turned down within moments.
Laughing gas does not provide pain relief after the appointment. If the treated tooth is sore later, ask the dentist or a pharmacist which pain relief suits your child's age and weight, and give it only as directed on the label.

About laughing gasWhat should you do after your child has had laughing gas?
- Expect your child to be back to normal quickly. Most children are alert within minutes of breathing oxygen, but a quiet afternoon is sensible.
- Offer a light snack first if they are hungry, unless the dentist has advised waiting because of the treatment or numbness.
- Watch for lip and cheek biting if local anaesthetic was used: children often chew or suck on a numb lip without realising. Our guide to how long dental numbness lasts explains what to expect.
- Follow the advice for the treatment itself, which matters more than the gas, for example after a filling or an extraction.
- Talk about the visit positively and praise something specific your child did; it shapes how they feel about the next appointment.
