Dental nitrous, also known as nitrous oxide or "laughing gas," is a type of sedation used in dentistry to help patients feel more relaxed and comfortable during dental procedures.
Nitrous oxide is a colorless, odorless gas that is administered through a small mask that fits over the patient's nose. The gas is mixed with oxygen and delivered in a controlled manner by the dental professional.
When the patient inhales the nitrous oxide, it enters the bloodstream and travels to the brain, where it produces a feeling of calm and relaxation. Nitrous oxide also has mild analgesic (pain-relieving) properties, which can help reduce discomfort during dental procedures.
One of the benefits of nitrous oxide is that it wears off quickly once the mask is removed, allowing patients to return to their normal activities without lingering sedative effects. The patient remains conscious and able to communicate with the dental professional during the procedure, but may feel more relaxed and less anxious.
Dental nitrous is considered safe and effective for most patients, although it may not be appropriate for those with certain medical conditions or who are pregnant. Your dentist can help determine if nitrous oxide is a good option for you based on your individual needs and medical history.
