Safe Sedation: Who’s a Candidate for Nitrous Oxide?

Did you know that sources estimate that anywhere from 15% to 36% of American adults have dental anxiety? That means you’re not alone if you’re dreading an upcoming appointment, whether it’s for a routine checkup and cleaning or a more complex procedure.

Fortunately, many dentists offer sedatives, like nitrous oxide, that can help you feel calm and comfortable throughout your appointment. However, not everyone is automatically a good candidate for this medication. Continue reading to learn more about who might benefit from this option!

What is Nitrous Oxide?

Popularly referred to as ‘laughing gas’, this colorless, odorless medication is administered via a mask that’s placed over your nose while your dentist works. It displaces the oxygen in your lungs and brain to reduce your body’s sensitivity to external stimuli. It’s known for inducing a deep sense of relaxation or even euphoria, and you might feel a tingly sensation in your limbs or catch a case of the giggles.

The drug kicks in within moments of inhaling the gas, but you won’t be ‘put to sleep’. Most patients remain aware enough to respond to their dentist’s questions or directions. Then, the effects dissipate just as quickly after the mask is removed, so you’ll likely be able to resume your normal activities after your visit.

Is Nitrous Oxide Safe?

This popular sedative has been used by doctors and dentists since the early 1800s, so its effects have been well-documented. It’s considered safe for most people, including children and elderly patients, when administered by a qualified professional.

However, that doesn’t mean that everyone is automatically a good candidate. Certain pre-existing health conditions and other factors can interfere with its effects or result in potential complications.  

Am I A Good Candidate for Nitrous Oxide?

There are certain prescription drugs and health concerns can cause problems if you undergo nitrous oxide sedation, so you must consult your dentist to ensure you’re a good candidate before proceeding. They’ll update your medical history and list any current medications or supplements that you’re taking to avoid doing anything that might have a negative effect.

You might not be approved for this sedative if you:

• Are in your first trimester of pregnancy.
• Have a stuffy nose.
• Have a chronic respiratory disease or bronchitis.
• Take certain prescriptions, like CNS depressants, opioids, or antihistamines.  
• Suffer from sleep apnea.
• Consumed alcohol prior to your appointment.

Having an honest conversation with your dentist is the best way to determine whether nitrous oxide sedation is right for you!
