Is Laughing Gas Dangerous?

Nitrous oxide (N2O) is a colorless gas that depresses the nervous system. It dulls pain and mildly alters awareness. Sounds may be distorted and some people report feeling numb or tingling limbs while inhaling this gas.

This may sound more like a street drug than a medical treatment. In reality, nitrous oxide, better known as “laughing gas,” is an effective and safe anesthetic used by many dentists for mild dental sedation to help relieve anxiety and make dental treatment more comfortable. But, go back nearly two centuries, and you’ll find that N2O was the complete opposite of a medical standard.

Soon after the discovery of this gas, it became a carnival attraction. Whole crowds would assemble to breathe in nitrous oxide and revel in the effects. When a dentist in the 1840s attempted to use nitrous as an anesthetic, he was ridiculed.

Nowadays, we know that recreational use of nitrous oxide can be dangerous. This is primarily because inhaling too much of the gas by itself can deprive your brain of oxygen.

Today’s dentists administer the gas in the safest way possible. The flow is combined with an oxygen tank so that the patients never lose too much air. Only trained dental professionals can give someone nitrous oxide.

On the plus side, nitrous has no residual effects and doesn’t accumulate in the system. Each dose is carefully measured and can be almost instantly reversed, if needed. It’s a very low-stress anesthesia technique that’s popular for children’s appointments.

The FDA regulates the use of nitrous oxide and you can rest assured that the controlled setting of a dental office is a safe place to use it. If you want to ease dental anxiety, ask your dentist whether laughing gas is right for you.
