Sedation Dentistry

What is Nitrous Oxide (Laughing Gas)?

Nitrous oxide — commonly known as laughing gas — is the most widely used and safest form of conscious sedation in dentistry. It's a colourless, odourless gas mixed with oxygen and delivered through a small, comfortable mask placed over your nose.

Within just 20 seconds of breathing it in, you'll feel a warm, relaxed, and slightly euphoric sensation — often described as a "warm fuzzy feeling." You stay completely awake and aware, but your anxiety fades, your pain threshold rises, and time seems to pass faster.

At Eastdale Family Dental, we offer nitrous oxide for patients of all ages — especially for children or adults who feel nervous, have a sensitive gag reflex, or simply want a more comfortable experience.

Simple & Comfortable

How Does It Work?

A Small Mask, That's It

A lightweight nose mask is placed over your nose. There are no needles, no injections, no pills — just a gentle flow of oxygen and nitrous oxide.

Fast-Acting — 20 Seconds

Nitrous oxide reaches the brain within 20 seconds. Within 2–3 minutes you'll feel relaxed, calm, and at ease. Our team can adjust the level in real time to keep you perfectly comfortable.

You Stay Awake & Alert

This is conscious sedation — you remain fully awake, can speak with Dr. Sarwara or Dr. Arora at any time, and are completely in control. You simply feel more relaxed.

Gone in 3–5 Minutes

When your appointment is done, we switch you to pure oxygen for a few minutes. The gas is completely eliminated from your body within 3–5 minutes. Most patients can drive themselves home.
