Learn how laughing gas works, what to expect during your appointment, and whether nitrous oxide is the right sedation option for you.
Nitrous oxide, commonly known as "laughing gas," is the mildest form of sedation dentistry and one of the most widely used. It's been safely used in dental offices for over 150 years.
How It Works
Nitrous oxide is a colorless, odorless gas that you inhale through a small mask placed over your nose. Within minutes, you'll feel a warm, pleasant sensation and a sense of calm. You remain fully conscious and can respond to your dentist throughout the procedure.
Benefits
- Fast-acting: Takes effect within 3-5 minutes
- Adjustable: Your dentist can increase or decrease the level of sedation during the procedure
- Quick recovery: Effects wear off within minutes after the mask is removed
- Safe for most patients: Including children and elderly patients
- No needles required: Administered through inhalation only
What to Expect
During your appointment, you'll breathe normally through the nose mask while your dentist works. You may feel lightheaded, tingly in your arms and legs, or experience a floating sensation. Some patients report feeling giggly — hence the nickname "laughing gas."
After the procedure, you'll breathe pure oxygen for a few minutes to clear the nitrous oxide from your system. Most patients can drive themselves home and return to normal activities immediately.
Is Nitrous Oxide Right for You?
Nitrous oxide is ideal for patients with mild to moderate dental anxiety, those undergoing routine procedures like cleanings or fillings, and anyone who wants to remain alert during their visit. It's not recommended for patients who are pregnant (first trimester), have certain respiratory conditions, or cannot breathe through their nose.
Consult with your dentist to determine if nitrous oxide sedation is appropriate for your specific situation.
