What Is Nitrous Oxide Used For?

Nitrous oxide is a sedative agent that dentists will often use to help patients to relax. Nitrous oxide is a mild form of sedation that is used for some dental procedures. Dentists will commonly use nitrous oxide, or “laughing gas,” for many dental procedures, including the following:

  • Filling cavities
  • Root canals
  • Tooth extractions
  • Routine examinations and cleanings

Filling Cavities

Nitrous oxide is now frequently used for patients who have teeth cavities, and many dentists will even offer deeper sedation for this and other relatively minor dental procedures.

Root Canals

Each of your teeth has a pulp-filled cavity in the root. If the pulp rots away or degrades, a root canal procedure will be necessary. Nitrous oxide is frequently used for this procedure, which involves a dentist going in and filling the cavity in the root with another material.

Tooth Extractions

There are many reasons that a person might have to have a tooth extracted. For example, a tooth that has decayed to the point that a dentist cannot repair or save will need to be pulled out.

Routine Examinations and Cleanings

Although not necessary for routine examinations and cleanings, many people who have anxiety over having dental work done will choose to have nitrous oxide prior to the treatment so that they can feel more relaxed and calm while the dentist is working. If you have small children who are anxious about the dentist, the use of laughing gas can be of great benefit to them as well.
