Nitrous oxide, often called laughing gas, is a mild sedative that helps you feel calm and comfortable during dental treatment. It works within minutes and wears off quickly after your visit.
Nitrous oxide is mixed with oxygen and breathed through a small, comfortable mask over your nose. Within a few minutes, most patients feel relaxed, warm, or pleasantly light, and anxiety fades. You stay awake and able to talk, breathe on your own, and respond to us throughout. We can adjust the level during treatment to keep you comfortable. Nitrous oxide doesn't replace local anesthetic, so we still numb the area for procedures that need it.

Nitrous oxide is a good option for mild to moderate dental anxiety, a strong gag reflex, sensitive teeth, and difficulty sitting still for longer appointments. It can also be used for children who need a little help relaxing, with a parent's consent. For patients with more severe anxiety or more complex procedures, deeper options such as IV sedation may be a better fit. We'll review your health history to make sure nitrous oxide is safe for you.
When treatment is finished, we turn off the nitrous oxide and have you breathe pure oxygen for a few minutes. That clears the gas from your system quickly. Most patients feel back to normal within minutes and can drive themselves home and return to work or school. We recommend eating a light meal before your visit, since a full stomach or an empty one can make some people feel queasy.
