For mild to moderate anxiety and short appointments - a cleaning, a filling, a single simple extraction - nitrous is usually the first option a practice reaches for. Published guides place it at $50 - $150 per visit, with some sources quoting $50 - $100 per hour, and it is billed as a separate line on top of the procedure.
What the published guidance says
Nitrous oxide is the lightest and least expensive sedation option, and the only one that lets you drive yourself home. Published clinical guidance says the calming effect starts within three to five minutes and that pure oxygen at the end flushes the gas out.

Frequently asked questions
Can I drive after nitrous?
Yes. Published guidance says pure oxygen is given at the end of the visit and it clears quickly, so you are not woozy and can drive. Oral and IV sedation do not allow this.
What does it cost?
Published 2025-2026 guides place nitrous at $50 - $150 per visit, or around $50 - $100 per hour where a practice bills by time.
Is it enough for severe anxiety?
Usually not. Where anxiety is severe or the procedure is long, published guidance points to oral conscious sedation or IV sedation instead.
