Nitrous oxide itself isn’t a substitute for a local anesthetic — it’s considered an anxiolytic, which means it makes anxiety disappear. For some procedures, you may still need an anesthetic injection. The difference is, you won’t mind. Yet, you won’t be asleep — you’ll be able to speak, be aware of what’s going on, and you will remain in control during the procedure. In fact, the dose can be fine-tuned to just the level of sedation you need.
When the procedure is over, the flow of nitrous oxide is decreased to zero, and the oxygen may be increased. After resting in the chair for a few minutes, you’ll be able to sit up, and soon you can resume normal activities like driving. Although the experience has been compared to “having a couple of drinks,” there is very little “hangover” effect afterward.
Most people whose anxiety would otherwise keep them out of the dental chair can benefit from conscious sedation with nitrous oxide. Before beginning treatment, we will take a complete medical history, including your use of both prescription and non-prescription medications. If you are pregnant, have COPD (Chronic Obstructive Pulmonary Disease) or some other pulmonary diseases, or are taking certain drugs, it may not be right for you. However, if you feel that you would benefit from a more stress-free experience in the dental office, ask about nitrous oxide conscious sedation.
