When children are having cavities filled, dentists sometimes opt to use nitrous oxide, commonly called laughing gas. If you’ve ever experienced this gas at the dentist before, you may remember the sensation that it provides. For some children, nitrous oxide reduces anxiety and distracts them from the pain associated with both getting that Novocaine shot in the gums and getting a tooth drilled. Nitrous oxide doesn’t work for all kids, and your dentist may opt to go with an orally administered sedative, instead. And of course, as with many things, not all dentists offer nitrous oxide, so it’s best to check beforehand.
