Why use Laughing Gas?

You are probably familiar with the idea of using laughing gas to calm you down during a dental appointment. This substance is safe to use for most patients, and it can be used during a variety of procedures to ensure that you remain comfortable. In addition, it is helpful for younger patients as it can lessen their apprehension, and may literally make them prone to giggling. We may use nitrous oxide, the official name of laughing gas, during certain procedures that may cause you anxiety.

How Does Laughing Gas Work?

The gas can be administered through a mask placed over your nose before treatment begins. Because of this, you are encouraged to try to breathe through your nose during the procedure. Nitrous oxide works quickly by making you feel calm, though it may also make you light-headed and euphoric. It may have a faintly sweet smell, but should not make you fall asleep, and you should still be able to talk to us if you have any problems or concerns during the treatment.

The mask will stay on for the entirety of your treatment, and it should not interfere with your breathing. Once we are finished with whatever procedure you are having, we can remove the mask, and the effects should wear off within a few minutes.

Are There Other Options Besides Laughing Gas?

Nitrous oxide is a common choice for many dentists. However, if you are not comfortable with using this gas, the option is typically voluntary. Because nitrous oxide is not a pain reliever, you will still need a local anesthetic to numb the pain. During more difficult procedures, nitrous oxide may not be sufficient, and you may need a sedative. You can discuss with us the best treatment option for you before your procedure is scheduled, to provide you with a more comfortable experience.
