Laughing gas (nitrous oxide) is a very safe way to help your child relax if he or she is a little nervous or anxious.  It’s inhaled through a “bunny nose” that is placed on your child’s nose during a dental procedure.  Laughing gas does not put your child to sleep – it’s just to help relax.  The effects are very short, so your child will feel back to normal before getting out of the dental chair.
