Nitrous oxide.
If the idea of the dental chair tightens your shoulders, you’re not alone — and laughing gas is a quiet, well-studied way to take the edge off. Here’s how it works at the Medical Park Drive office.
What It Is
A gentle, breathable sedative.
Nitrous oxide — the “laughing gas” you may have heard about — is a colorless, sweet-smelling gas that you breathe through a small soft mask placed over your nose. It’s mixed with oxygen in our office at a ratio of at least 30 percent nitrous and the rest pure oxygen, which keeps the dose well within the range that has been used safely in dentistry for decades.
You stay awake. You can hear, talk, and respond the entire time. Most patients describe a mild floaty calm rather than anything dramatic. Some doze lightly and don’t remember much of the visit; others notice mild tingling in the hands and feet. Both are normal.
Onset is fast — typically within a few minutes — and so is offset. After your visit we run pure oxygen for about five minutes, by which point most patients are clear enough to drive themselves home.
Who It Helps
Why patients ask for it.
- Onset is quick — relaxation typically arrives within a few minutes of breathing it in.
- Wears off as soon as you stop. Most patients drive themselves home.
- Adjustable mid-visit. We can dial it up or down based on how you're feeling.
- Helps with a strong gag reflex, which makes scans, X-rays, and back-tooth work easier.
- Doesn't replace local anesthetic — it's used alongside it for added comfort.
When It’s Not the Right Choice
Tell us first.
Nitrous is well tolerated by most adults and most children, but it isn’t for everyone. Please mention any of the following on your medical history form — we may suggest skipping it or suggest a different comfort approach:
- Chronic obstructive pulmonary disease (COPD) or significant emphysema
- Difficulty breathing through your nose (a heavy cold, severely deviated septum)
- First-trimester pregnancy
- Recent middle-ear surgery, current sinus infection, or pneumothorax
- Certain cobalamin (B12) deficiencies — please mention any active treatment
The list above is informational, not exhaustive. Your full medical history, current medications, and prior reactions matter — please share everything so Dr. Podbesek can make a recommendation that fits your situation.
Try It Without Committing
A five-minute trial, then you decide.
If you’re curious but uncertain, ask for a five-minute trial at the start of your appointment. We turn the gas on briefly so you can feel the effect and decide whether to use it for the rest of the visit. There’s no pressure either way.
