Nitrous Oxide inhalation is safe and is used to relax your child and reduce their sensation to pain during their dental procedure. Your child will remain awake while the gas is administered. After the procedure is finished, we will assure that they breathe oxygen in order to clear the Nitrous Oxide from their lungs. Once your child's procedure is over, they should be fine to resume their normal activities with no lingering side-effects of the Nitrous Oxide. We base our use of Nitrous Oxide on your child's age, anxiety level, gag reflex and the extent of the procedure we are performing on them.
