Which procedure is typically enhanced by the use of nitrous oxide?

The use of nitrous oxide, commonly known as laughing gas, is particularly beneficial in procedures that may cause anxiety or discomfort to patients. In the context of tooth extraction, this sedation technique can significantly alleviate anxiety and enhance patient comfort during the procedure. Nitrous oxide works by inducing a calming effect, allowing patients to feel more relaxed and less aware of any discomfort that may occur during the extraction process.

While nitrous oxide can also be used in other dental procedures, like root canals or cavity fillings, tooth extractions often involve a higher potential for anxiety due to the invasiveness and expectation of discomfort associated with the removal of a tooth. Therefore, the option referring to tooth extraction is the most appropriate in this context.
