Nitrous oxide, often called “laughing gas,” is mixed with oxygen and breathed through a small nose mask. It can help you relax within minutes while you remain awake and able to respond. When treatment ends, we give you oxygen and check your recovery before you leave. Local anesthetic may still be needed to numb the treatment area.
A small mask rests on your nose. You breathe normally while we adjust the blend. The sedative is inhaled, although dental treatment may still involve local anesthetic injections.
You may notice relaxation, light-headedness, or tingling within a few minutes. Tell us how you feel so we can adjust treatment as needed.
You remain awake and able to respond. Let us know if you feel uncomfortable; we can adjust or stop the nitrous.
We give you oxygen and check that you have recovered. Most patients can drive after nitrous alone once cleared, but your dental procedure may still require recovery time.
Nitrous may help with dental anxiety, a sensitive gag reflex, or a longer appointment. If it is not suitable or does not provide enough relief, we can discuss other comfort arrangements or referral. Oral sedation and IV conscious sedation may be considered after a health review and discussion of the procedure and recovery needs.
Nitrous has a long history of use in dentistry, but it is not suitable for everyone. We review your health, medications, and ability to breathe through your nose, and explain potential side effects such as nausea or dizziness. Tell us if you are pregnant or have any change in your health before treatment.
