Nitrous oxide sedation was first utilized in a medical setting in 1844. Throughout the late 19th and early 20th century, researchers and physicians experimented with its properties and effects, eventually leading to it first being used by a dentist in the early 1980’s. Today, it’s trusted by millions of patients and dentists to help create a relaxing and positive environment for those who are anxious, fearful, or require lengthier treatments. Unfortunately, over the decades, many myths have also popped up about this service, shaping patients’ feelings about it. Read on to debunk the myths you may have heard about nitrous oxide sedation so you can stick to the facts!

Myth #1: It’ll Make You Laugh Uncontrollably

You’ve likely heard of nitrous oxide sedation referred to as “laughing gas” because it makes you laugh during your entire appointment. The truth is that this nickname is a misnomer! Nitrous oxide won’t have you laughing so hard you need to catch your breath during your procedure. It actually causes a euphoric wave to wash over you, helping reduce your anxiety and fear, but not to the point where you lose control of yourself.

Myth #2: You’ll Be Telling All of Your Secrets to Your Dentist

Nitrous oxide doesn’t work like a truth serum, despite that being a common rumor. While you may answer questions that your dentist asks you during your procedure or tell a funny story, you’ll remain in control of what you say and do. Although, you may feel the desire to talk more than you usually would since you’ll feel at-ease!

Myth #3: The Effects Can Take a Long Time to Wear Off

Nitrous oxide dental sedation in Arlington is unique in the fact that the effects actually wear off quickly! The sedation will be administered during your visit until your cleaning or procedure is complete. Once our team shuts off the sedation, you’ll begin feeling the effects wear off within moments. After a few short minutes, you’ll feel well enough to drive yourself back to work and go on with your day without any downtime.

Myth #4: Few Patients Can Benefit from It

You may be surprised to learn that nitrous oxide can actually help a number of patients who experience different barriers to feeling comfortable in the treatment chair. Whether you have a sensitive gag reflex that makes cleanings difficult, you’re in need of a longer treatment, you have a disability that makes sitting in the dental chair uncomfortable, or you experience mild or moderate dental fear or anxiety, you can benefit from nitrous oxide sedation. Before the sedation is administered, your dentist will make sure you’re a good candidate by reviewing your medications and medical history.
