Laughing Gas

Nitrous Oxide

“Laughing gas,” nitrous oxide is a very safe, mild sedative that helps the  child to remain relaxed during dental procedures. Your child’s dentist will give the sedation with the use of a “space mask,” which carries air (oxygen) mixed with the medication. Your child will be asked to breathe through the nose, not the mouth, and will sense a faint, sweet smell. The sedation will take effect in about 5 minutes.

The mask will remain in place until the procedure is done. Most kids are awake during the entire procedure and may have a “happy” feeling and are all realxed, sometimes they may briefly sleep which could be just because they are so realxed. The doctors are constantly observing to make sure the kids are breathing normally. When the procedure is complete, the nitrous oxide will be turned off and your child will breathe in pure oxygen for about 5 minutes to clear out any remaining gas. You should limit your child to a very light meal before this procedure, such as toast or a bagel.
