Nitrous Oxide/Laughing Gas

Some children are given nitrous oxide (laughing gas) during the placement of sealants or dental treatment to relax them for their procedure. Nitrous oxide is given through a small breathing nose, allowing them to relax, but without putting them to sleep. The American Academy of Pediatric Dentistry recognizes this technique as a very safe, effective technique to use for treating children’s dental needs. Nitrous oxide is not effective in children who are too young or too anxious to sit in the chair and have the nosepiece placed on their nose.
