Nitrous Oxide, more commonly known as happy gas or laughing gas, is an extremely popular form of sedation for dentists and their patients.Because nitrous oxide usually won’t put you to sleep, it makes the procedure easier for the dentist as he can give you instructions. Meanwhile, the nitrous oxide gas keeps you feeling relaxed and calm throughout.

How It Works

Nitrous oxide is administered via a mask placed over your nose. A machine controls the flow and combination of the gas and oxygen for a precise dose and controllable effect. For safety reason, the machine cannot deliver a mix containing more than 70% of nitrous oxide. Usually the mix contains between 50% and 70% oxygen.

Depending on the dose and the patient, you may still fall asleep. If you do sleep, you may find you forget the entire procedure afterwards. Whether asleep or awake, you shouldn’t feel pain, discomfort or anxiety throughout the procedure. Even though nitrous oxide does have some pain relief properties, most patients would also require local anaesthetic to numb the area being treated.

Once the procedure is complete, the gas is simply switched off.

Recovery

As soon as the flow of gas is cut, you will find the effects beginning to wear off. In a couple of minutes, you will be completely recovered from the sedation (although possibly not the treatment itself) and may be able to leave.
