— Child Dental Anxiety Treatment
Your child refuses to sit in the dental chair. You’ve been postponing appointments for months. You’re not alone.
Dental anxiety in children is common, real, and not something a child can simply be talked out of. It is not a behaviour problem. It is a fear response — often triggered by a previous difficult appointment, by something they’ve heard, or simply by the unfamiliarity of the environment, the sounds, and the equipment. Telling a frightened child to “be brave” rarely changes anything. Changing how the appointment feels is what works.
Nitrous oxide — laughing gas — is the most widely used tool in paediatric dentistry for exactly this reason. It does not eliminate the child’s awareness. It changes the experience of the appointment: the anxiety is lower, the time passes differently, and the child often finishes without having found it nearly as difficult as they feared. More importantly, they leave without a new traumatic memory to carry into the next visit.
At Tricity Smiles, nitrous oxide is available as an add-on to any paediatric appointment — a pulpotomy, a crown, a filling, an extraction, or even just a check-up for a child who needs a gentle introduction to the clinic. It is not a last resort. It is a straightforward clinical tool, and Dr. Sandhu trained in its use as part of his paediatric programme at USC and UCSF.

What nitrous oxide actually does — and what it doesn’t
Three things parents need to understand before the appointment. Nitrous oxide is the mildest form of dental sedation available — and the one most misunderstood.
Conscious Sedation
The Nasal Hood Goes On
A small, comfortable nasal hood is placed over your child’s nose — no mask over the mouth, no injection, no discomfort. Dr. Sandhu introduces it as part of the tell-show-do process: the child sees it, holds it, and understands what it does before it goes on. For many children this is the moment the appointment turns.
Not a Painkiller
It Reduces Anxiety. Local Anaesthesia Numbs the Tooth.
Nitrous oxide raises the pain threshold and reduces the emotional response to dental treatment — but it does not replace local anaesthesia for procedures that require it. The combination of nitrous and a numb tooth is what makes a difficult appointment manageable.
Fastest Recovery
Fully Worn Off Before Your Child Leaves
Unlike oral sedation or IV sedation, nitrous oxide clears from the body within 5 minutes of being replaced with 100% oxygen at the end of the appointment. There is no residual drowsiness, no escort requirement, and no afternoon of watching your child sleep it off.

What happens during a nitrous oxide appointment
Four steps. From the moment the nasal hood goes on to the moment your child leaves — fully recovered, often wondering what all the worry was about.
01
The Nasal Hood Goes On
A small, comfortable nasal hood is placed over your child’s nose — no mask over the mouth, no injection, no discomfort. Dr. Sandhu introduces it as part of the tell-show-do process: the child sees it, holds it, and understands what it does before it goes on. For many children this is the moment the appointment turns.
02
The Gas Takes Effect
Within 3 to 5 minutes, most children describe a warm, tingling sensation — sometimes a feeling of floating or lightheadedness. The anxiety drops. The perception of time changes. A child who was rigid in the chair begins to relax. The level of nitrous oxide is adjusted throughout to keep the child comfortably sedated but fully conscious.
03
Treatment Is Completed
With the child calm and cooperative, the dental treatment proceeds normally. Local anaesthesia is still used where required — the child feels the numbing but is rarely distressed by it. The tell-show-do approach continues throughout. Most children complete treatment without incident that would have been impossible to start without nitrous oxide.
04
Recovery in the Chair
At the end of the appointment, the nitrous oxide is switched off and replaced with 100% oxygen for 5 minutes. The child is fully alert before leaving the chair. There is no grogginess, no need to be carried to the car, and no afternoon of recovery at home. The child can eat, drink, and return to normal activity immediately.

Which children are suitable
— and which are not
Nitrous oxide is suitable for most children aged 3 and above. Dr. Sandhu reviews medical history at every consultation before recommending it — there are some situations where it is not appropriate, and these are identified before the appointment, not during it.
The most important requirement is simply that the child can breathe comfortably through their nose and tolerate wearing the nasal hood. For most children this is straightforward. For a child who is severely blocked or has active ear, nose, or throat conditions, the appointment may need to be rescheduled.
If you are unsure whether your child is suitable, mention any medical conditions, medications, or respiratory history when you book. Dr. Sandhu will confirm suitability at the consultation appointment — well before any treatment is planned.

— Our Philosophy
A child who finishes the appointment without a bad memory comes back next time.
The appointment that goes well does something beyond fixing a tooth. It builds a piece of the child’s relationship with dentistry — one that will follow them for decades. A child who leaves without fear is more likely to come back before the next problem becomes urgent. They are more likely to tell their parents when something hurts. They are less likely to become the adult who avoids the dentist until there is a crisis.
“The goal of using nitrous oxide is not just to get through today’s appointment. It’s to make sure today’s appointment doesn’t make the next one harder.”
— Dr. Sandhu
This is why we use nitrous oxide readily at Tricity Smiles — not as a last resort for the most extreme cases, but as a standard tool for any child for whom it would make the appointment better. A dentist who reserves sedation only for children in full meltdown is a dentist optimising for their own convenience rather than the child’s experience.
A calm appointment is not a soft option. It is the clinical standard for paediatric dentistry done properly. It is what Dr. Sandhu was trained to deliver at USC and UCSF. And it is what your child deserves from the very first visit.
— FAQ
What parents ask us about laughing gas for kids
Common questions about safety, suitability, what to expect, and how to prepare your child for the appointment.
Is laughing gas safe for children?
Yes. Nitrous oxide has a 150-year safety record and is endorsed by the American Academy of Pediatric Dentistry for use in children. It is the mildest form of dental sedation — the child remains fully awake and responsive throughout, and the effects wear off completely within minutes. It is safe for children aged 3 and above with no significant medical contraindications.
Will my child be unconscious?
No. Nitrous oxide is conscious sedation — your child remains fully awake, can talk, follow instructions, and respond normally. It reduces anxiety and the perception of time, but does not put the child to sleep. This is one of its key advantages over deeper sedation.
How quickly does it work, and how quickly does it wear off?
Nitrous oxide takes effect within 3 to 5 minutes of being inhaled and wears off completely within 5 minutes of switching to 100% oxygen at the end of the appointment. Unlike oral or IV sedation, there is no residual drowsiness. Your child can eat, drink, and resume normal activity immediately after leaving the clinic.
Does nitrous oxide replace the injection?
No. Nitrous oxide reduces anxiety and raises the pain threshold, but it does not numb the tooth. Local anaesthesia is still used for any procedure that requires it. The combination of nitrous oxide and local anaesthesia gives a child who is both calm and completely numb — which is what makes complex appointments manageable.
What ages is it suitable for?
Nitrous oxide is suitable for most children aged 3 and above who can breathe comfortably through their nose and cooperate with wearing the nasal hood. It is particularly effective for children aged 5 to 12 with mild to moderate dental anxiety. Dr. Sandhu will assess suitability at the consultation.
How much does laughing gas for kids cost in Chandigarh?
Nitrous oxide sedation at Tricity Smiles starts from ₹4,000 per session and is added to any treatment appointment. The cost is confirmed before treatment begins.
Are there children who should not have nitrous oxide?
Nitrous oxide is not suitable for children with significant respiratory conditions, certain ear and sinus conditions, a history of recent ear surgery, or vitamin B12 deficiency. Children with severe phobia who cannot cooperate at all may require specialist referral for deeper sedation. Dr. Sandhu reviews medical history before recommending nitrous oxide at every appointment.
Can it be used for my child’s first dental visit?
It can — but for a first visit involving only a check-up and clean, it is usually not necessary. For a first visit where treatment is also needed, nitrous oxide can make a significant difference to how the child experiences and remembers the appointment. Dr. Sandhu will discuss this before booking.
Preparing for the Appointment
How to prepare your child
A well-prepared child almost always has a better appointment. Here is what to do — and what to avoid — before the visit.
Before the Visit
- Give a light meal 2 hours before the appointment — not a heavy meal, not an empty stomach
- Tell your child about the “special air through a little nose mask” in a calm, matter-of-fact way — no drama in either direction
- Mention that Caesar might be there — for many children this is the detail that shifts the mood
- Arrive a few minutes early so there is no rushing
- Let us know if your child has a cold or blocked nose on the day — we may need to reschedule
Avoid
- A heavy meal in the 2 hours before — nausea is rare but more likely on a full stomach
- Telling your child the appointment “won’t hurt” — if local anaesthesia is involved, they may feel the injection and lose trust
- Describing the dentist as scary to other people in front of the child
- Bringing a sibling who had a difficult dental experience — it transfers
After the Appointment
- Your child can eat and drink normally — no recovery period
- Normal activity resumes immediately
- Talk positively about what happened — reinforce the experience as a good one
On the day: If your child wakes up with a blocked nose, a fever, or an ear infection — call us before you come in. Nitrous oxide on a blocked nose does not work well and the appointment may need to be rescheduled. We would rather know in advance.
The appointment your child won’t dread — every time.
Add nitrous oxide to any paediatric appointment at Tricity Smiles. Dr. Sandhu will confirm suitability and walk you through the preparation before the day arrives.
