WHY DO DENTISTS USE LAUGHING GAS?Laughing gas, whose chemical name is Nitrous Oxide, is a non-flammable, colorless, and invisible gas that dentists use during dental procedures. It is a safe and common sedative used for various dental procedures. Below are 7 reasons why dentists use this gas.

Helps to calm patients

Dental patients who suffer from anxiety, fear of needles, or children who cannot still feel relaxed and calm after inhaling this gas. It becomes easy for the dentist to perform a dental procedure without interruptions.

It is Extremely Safe

Using laughing gas does not affect the patient's internal organs like the liver, heart, and lungs. It is also safe for children above the age of 3.

Works Quickly

The patient, within minutes, feels the calming effect of laughing gas. Its immediate effect saves both the dentist's and the patient's time.

Its Effects Wear off Quickly

After completing a dental procedure, the effects of laughing gas on a patient last for about 3-5 minutes. The patient breathes in pure oxygen through a mask. The dentist does not have to keep an eye on the patient for long. The patient is also fit to continue with their daily activities after leaving the dentist's office.

Patient is Active

Laughing gas does not put a patient to sleep. The patient is awake during the dental procedure. The dentist can therefore ask questions and express any concerns during the procedure, and the patient will be able to respond.

Simple Administration

Administration of laughing gas is quite easy. It is administered through a mask that fits the patient's nose. It is then absorbed into the lungs. This method is perfect for patients who for needles as it is not administered through injections.


Many dentists prefer using laughing gas as their main anesthetic option to ensure that dental procedures go smoothly, and patients have pain-free visits.
