Nitrous oxide, known to many as laughing gas, is commonly used to ease anxiety. It is administered by inhaling the gas while carefully being monitored. You will feel like you are in a euphoric and completely relaxed state. The feelings of fear and anxiety will fade away while you peacefully relax during your dental treatment.
Nitrous oxide is very safe and effective. Once the procedure is over, it will wear off fairly quickly and you should be able to drive yourself home.
