You’re likely familiar with what happens at a standard dental checkup and cleaning: your dentist will remove tartar, polish your teeth, and maybe even take an X-ray to look for cavities. But what about the more intensive procedures? In these cases, a dentist may use nitrous oxide, commonly known as laughing gas, to keep you comfortable and relaxed during your stay. Here’s what you need to know about this frequently used sedative.

How Does Laughing Gas Work?

Nitrous oxide is a colorless, odorless gas often used by dentists as an alternative to full sedation. The gas is administered through a mask fitted over your nose. When you inhale the mixture, which is typically 30% nitrous oxide and 70% oxygen, the gas displaces the air in your lungs and keeps oxygen from getting to your brain. The subsequent feeling of lightheadedness helps you remain calm during invasive procedures, though you’ll remain conscious and able to speak. When the procedure is over, the mask is removed, and the effects of the gas should wear off within minutes.

Are There Any Side Effects?

Typically, patients can resume normal activities, such as driving, after being administered laughing gas. However, some lingering side effects, while rare, are possible. For example, your dentist may recommend eating light meals prior to the procedure and avoiding any big meals three hours afterward in case nausea sets in. Headaches, fatigue, excessive sweating, and shivering are also possible.

Nitrous oxide is safe, but certain patients may benefit from other forms of sedation. Pregnant women, for instance, may be advised against it. Additionally, those with congestion or trouble breathing through their nose may not experience the intended calming effect. Your dentist will let you know if you’re a good candidate for laughing gas after a preliminary visit.
