What is a common use of nitrous oxide in dentistry?

In dentistry, nitrous oxide is primarily used as a sedative agent. It is commonly referred to as "laughing gas" due to its euphoric effects, which help to alleviate anxiety and discomfort that patients might experience during dental procedures. When administered, nitrous oxide induces a feeling of relaxation and can make patients more comfortable and less aware of their surroundings, which is particularly beneficial for those who may have dental phobias or anxiety.

The sedative properties of nitrous oxide allow dental professionals to perform procedures smoothly and efficiently, as patients are more cooperative and relaxed. Additionally, it is a fast-acting and easily reversible agent, making it suitable for use in a clinical environment where patients need to recover quickly after the procedure.

While other substances might be used for local anesthesia, disinfection, or pain relief, nitrous oxide's unique role in sedation stands out as its primary use in dental practice. This positioning enhances the overall experience for patients, promoting a more positive association with dental visits.
