Nitrous oxide gas (laughing gas) is given to help anxious patients relax prior to treatment. Prior to receiving nitrous oxide it is important to not eat or drink anything two hours prior to the appointment. At the time of appointment it is essential to inform the dental team of any change in medical history. Nitrous oxide has long been used in dentistry and is a safe, reversible anxiolytic.
For apprehensive patients, it is possible to provide medications that will result in conscious sedation. Drowsiness often results from consuming these medications, and it is important to arrange for transportation to and from the dental office.
