Does going to the dentist get your heart pumping? You may have a dental phobia that makes it harder to get the oral care you need. Thankfully, there are ways you can feel calmer and more at ease. Nitrous oxide is an effective solution for many patients in Nepean, but is it really safe for you? You might have this question if you’ve never had it before, so here’s what you should know to feel your best about it.

What Is Nitrous Oxide?

In short, nitrous oxide, also called laughing gas, is a form of dental sedation that helps you relax using medication. It’s a gas you breathe in that’s a mix of nitrous oxide and oxygen. You wear a mask over your nose, and you should start to feel it after a few minutes. Many people say they feel floaty or euphoric.

You might think it’ll render you unconscious, but this isn’t the case. You will still be awake and aware of your surroundings. You’ll be able to follow directions and answer any questions. But patients often feel so at ease that they doze off on their own! If that’s true for you, then you can be woken up with a couple of light nudges. Once you stop breathing in nitrous oxide, it will take just a few minutes to feel back to normal.

Is Laughing Gas Really Safe?

Laughing gas is an effective solution for many people, and it has been tested thoroughly to ensure it’s safe for nearly everyone. Kids and adults get it because it helps them relax without disrupting their day. You can drive yourself home right after, and there are often no side effects. A few people might feel dizzy or nauseous, but it goes away as they stop inhaling it.

Dental sedation is an effective way to relax, but it’s not suitable for a small group of patients. For instance, those with allergies to the medication, who are expecting, and who have respiratory problems may not be eligible to get it. The good news is your dentist will clear you for it and ensure it’s the right fit for you.

Should I Get Nitrous Oxide?

Nitrous oxide is a great solution for those with dental phobia, but it’s often best for those who have a strong gag reflex, have sensitive teeth and gums, struggle with sitting still, and deal with mild to moderate anxiety. By letting your dentist know about what your reservations are, you can learn whether conscious sedation can be helpful while you get the oral care you need.
