About Nitrous Oxide


Nitrous oxide, commonly known as "laughing gas," is a widely used form of sedation in dentistry, including at our Indianapolis and Fishers, Indiana office at Martin Dentistry. This safe and time-tested sedative has been utilized by dentists for decades, both for routine check-ups and more complex dental procedures.

Nitrous oxide is a colorless, odorless gas that, when inhaled, induces a state of relaxation within minutes. Our team of experienced general and cosmetic dentists, Dr. Matt Martin, Dr. Stephanie Martin, Dr. Lynn Marshall, and Dr. Lindsey Garrison, along with our dental assistants, carefully monitor and adjust the level of nitrous oxide to ensure a customized and comfortable sedation experience, alleviating any pain or anxiety.

After the procedure, the effects of nitrous oxide wear off quickly, allowing patients to return to their normal activities, including driving themselves home, without any lingering sedative effects.

What to Expect

Typically, nitrous oxide is combined with oxygen for safer results. To begin sedation, the dentist places a nasal hood over the patient’s nose and the patient is instructed to breathe normally through their nose in order to inhale the gas. The nitrous oxide will start working within a few minutes and the patient will begin to feel light-headed. After that, the patient will notice a tingling sensation, usually in their arms and legs, or a vibrating feeling that is followed by a warmth through the body. Once the gas takes full effect, the patient should experience a sense of euphoria, or well-being. Unlike other forms of sedation, the dentist can determine the exact amount of time that the nitrous oxide is needed. Therefore, it can be switched on and off at any given time, depending on the patient’s needs.

Treatment Aftercare

Once the dentist has stopped the supply of nitrous oxide, the gas should leave the body within 3 – 5 minutes, which means that the patient should have no “hangover” effect and is safe to drive home after the procedure. Since nitrous oxide is a relatively safe form of sedation, there are usually no negative side effects associated with the gas. In rare instances, a patient may report slight nausea. If a patient is prone to nausea, it is suggested they eat something before receiving nitrous oxide.
