Nitrous oxide, which is more commonly known as laughing gas, is a colorless, non-flammable gas that has a range of different uses. In the world of dentistry, nitrous oxide is an extremely valuable sedation tool that is used to help certain types of patients tolerate dental treatments.

How is nitrous oxide used in sedation dentistry?
There are various levels of sedation used in sedation dentistry. These range from placing a patient on the very edge of consciousness with no awareness of what is happening around them to very mild sedation that calms the patient, but they retain full comprehension of their surroundings. Nitrous oxide falls into the latter category and is the mildest form of sedation currently used in dentistry.

Nitrous oxide is administered via a mask that is placed over the patient’s nose for the duration of the procedure. Despite its name, it doesn’t actually make you laugh. Instead, it induces a fairly euphoric state that is sufficient to make the patient feel calm and relaxed. The effects of nitrous oxide last only as long as the patient is inhaling it. As soon as inhalation ceases, it takes less than a minute for the patient to return to feeling normal.

Patients are monitored the entire time that they are under sedation so that the nitrous oxide can be removed immediately if required. This makes it extremely safe.

Who can benefit from the use of nitrous oxide in sedation dentistry?
As we know, nitrous oxide is the lightest form of sedation currently available. It is primarily recommended for patients who:
  • Have only a mild fear or concerns about undergoing a dental procedure
  • Are having a very simple, non-invasive or minimally-invasive dental procedure such as a check-up, a professional clean or a filling
  • Have mild physical or cognitive disabilities that make it difficult for them to sit still or follow instructions during a dental appointment
