Nitrous Oxide, or laughing gas as it is commonly referred to, is a very safe and effective tool for helping patient’s feel comfortable.  Laughing gas is well-tolerated and it reduces pain and anxiety. It helps kids to relax and sit still which reduces contamination when placing fillings.  This in turn increases the longevity of our fillings.  Using laughing gas will help put your child at ease during a treatment but will not put your child to sleep. We recommend that patients NOT have a large meal prior to their appointment with laughing gas.
