Nitrous Oxide is commonly referred to as “laughing gas” as it can make patients feel happy, relaxed, and calm during their procedure. A breathing mask is placed, and the nitrous oxide along with oxygen is released in the mask. The effect works quickly- in a matter of minutes you may begin to feel relaxed and calm for your dental procedure. Once the procedure is complete, the nitrous oxide mask is removed, and the “laughing gas” is out of your system in a few minutes, so you are able to drive yourself home. This is a great technique for those with mild anxiety, or for children requiring dental work such as fillings.
