Sedation Dentistry - Nitrous Oxide

Nitrous oxide, also known as laughing gas, is a safe and effective gas that is used to reduce dental anxiety in patients and has some pain relief properties. The physiological effects of nitrous oxide lasts for approximately one minute per lungful and will dissipate. Some residual effects may last up to several minutes later. Nitrous gas works by infusing into the membranes of the body and produces an anesthetic effect.

The benefits of nitrous oxide are many, and the risks are few. The gas is administered with a comfortable mask placed over the nose, and the patient is instructed to breathe in through the nose and out through the mouth. After the gas is adjusted to the appropriate dose, and the patient is relaxed and sedated, the dentist can comfortably give the anesthetic injection (if needed) to the patient, and then proceed with dental treatment. After the treatment is completed, the patient is given pure oxygen to breathe for a few minutes, and all the effects of sedation are usually reversed. Unlike IV sedation or general anesthesia, the patient can almost always leave the office by themselves, without an escort. Nitrous oxide is one of the safest anesthetics available.
