Watch any scene from a sitcom or comedic movie that takes place in a dentist's office, and without fail, you'll see characters inhale "laughing gas" and begin giggling uncontrollably. That gas, of course, is more commonly known as nitrous oxide (N2O) and has been used as a sedative for dental procedures for more than a century.
How Does Nitrous Oxide Work?
Mixed with oxygen and inhaled through a mask that fits over the nose and mouth, nitrous oxide helps to reduce patients' discomfort during dental procedures by slowing down the body's response to pain and minimizing anxiety by producing feelings of relaxation and euphoria. Additionally, nitrous oxide is known to help to reduce the gag reflex, making it easier for dentists to perform certain procedures.
Is Nitrous Oxide Still Used by Dentists?
Yes, nitrous oxide is still used as a sedative during dental procedures. Though other sedation options, such as oral sedation and intravenous (or IV) sedation, have become popular in recent years, nitrous oxide remains a popular and commonly used sedative due to its safety, effectiveness, and ease of use.
A benefit of nitrous oxide beyond its effectiveness and safety is that its effects wear off quickly upon removal of the breathing mask from the face, allowing patients to resume their normal activities almost immediately after a procedure.
Are There Scenarios in Which Nitrous Oxide Is Not Safe or Appropriate?
Nitrous oxide may not be safe or appropriate in the following scenarios:
- Pregnancy – nitrous oxide can have potentially harmful effects on a developing fetus
- Respiratory conditions – such as emphysema or chronic obstructive pulmonary disease
- Head injuries – due to the increased intracranial pressure brought about by nitrous oxide
- Substance abuse issues – nitrous oxide can be habit-forming
- Allergic reactions – some people have an allergic reaction to nitrous oxide
