The Truth About That Viral Airplane Ear Steaming Trick All Over Your Feed
Sep 16, 2025By Samira Reddy
Dental visits don’t have to be a battle anymore. For many children, fear of the dentist stems from sounds, sights, and sensations they don’t understand. But thanks to advances in pediatric dentistry, tools like laughing gas (nitrous oxide) and virtual reality (VR) goggles are helping turn tearful appointments into positive, even enjoyable experiences.
What Is Laughing Gas?
Laughing gas, or nitrous oxide, is a colorless, odorless gas that has been used in dentistry for decades. When inhaled through a small mask placed over the nose, it helps reduce anxiety, dull pain perception, and create a sense of calm and well-being.
In children, laughing gas:
- Acts quickly and wears off within minutes after the mask is removed.
- Doesn’t put the child to sleep, but keeps them relaxed and responsive.
- Allows the dentist to complete treatments like fillings or cleanings with minimal stress for the child.
It’s one of the safest and most effective options for managing mild to moderate dental anxiety in children, especially during short procedures.
What Are VR Goggles in Dentistry?
Virtual reality (VR) goggles immerse children in a calming digital environment while they’re sitting in the dental chair. Instead of watching the dentist work or hearing unfamiliar noises, the child gets to:
- Watch cartoons, calming nature scenes, or interactive games.
- Block out the sights and sounds of the clinic.
- Focus their attention on something fun instead of the procedure.
VR distraction therapy has been shown to significantly reduce dental anxiety, especially in children aged 4–12. It works best for children undergoing routine procedures like cleanings, fluoride application, or even minor fillings.
Why Are These Tools So Effective for Kids?
Both laughing gas and VR work on the same basic principle: they shift the child’s focus away from fear.
Laughing gas:
- Reduces the body’s physical response to stress.
- Makes the child feel “floaty” and happy, often leading to giggles or silliness—hence the name.
- Increases cooperation and reduces fidgeting or crying.
VR goggles:
- Provide visual and mental distraction from sights, sounds, and sensations.
- Help children stay calm and still.
- Give kids a sense of control, as they can choose what they watch.
When used together, they can create an almost magical transformation in how a child experiences dental treatment.
Which Children Benefit the Most?
These techniques are especially helpful for:
- Children with mild to moderate dental anxiety.
- Kids undergoing their first dental procedure.
- Children with strong gag reflexes or sensory sensitivities.
- Special needs children who respond well to visual and auditory engagement.
- Kids who have had a bad past experience with a dental drill or injection.
While not every procedure is suited for VR or laughing gas, many routine treatments can be made smoother with these approaches.
Safety and What Parents Should Know
Laughing gas is extremely safe when administered by trained pediatric dentists. The dose is carefully adjusted based on the child’s age and weight. After the procedure, oxygen is given for a few minutes to wash the gas out of the lungs, your child is typically back to normal within 5–10 minutes.
VR goggles are sanitized between uses, and the dentist monitors the child continuously to ensure they remain comfortable. Most VR content is pre-approved and child-safe.
Before the appointment, it’s good to:
- Avoid heavy meals for at least 2 hours before using laughing gas.
- Inform the dentist about any respiratory issues, recent illness, or medication allergies.
- Let the child know the goggles are like “watching cartoons in space” to build excitement.
Real Benefits for Parents Too
- No need for sedation or general anesthesia for minor procedures.
- Fewer tears and struggles in the chair.
- Shorter appointment times thanks to better cooperation.
- Better treatment outcomes because the dentist can work without interruptions.
- Positive dental associations, making future visits easier.
Final Thoughts
Dental anxiety doesn’t have to define your child’s relationship with oral health. With tools like laughing gas and VR distraction, dental visits can become a positive experience, even something your child looks forward to.
If your child has shown fear or hesitation in the past, talk to your pediatric dentist about these options. A calm child, a relaxed parent, and a smooth procedure, that’s the kind of dental visit everyone can smile about.
