What Is Nitrous Oxide?

Nitrous oxide is a gas mixed with oxygen and used for minimal sedation during dental treatment. It is often called laughing gas.

How Laughing Gas Works

You breathe the gas through a small nasal mask. It can help you feel calmer and more relaxed while you remain awake and can talk to the dentist.

What It Feels Like

You may feel relaxed, light, warm, or slightly sleepy. The effects usually begin quickly and wear off soon after the gas is stopped.

Who Nitrous Oxide Sedation Helps

Nitrous oxide may be suitable for some patients who find dental treatment difficult or stressful.

Patients with Dental Anxiety

Nitrous oxide can help reduce feelings of anxiety during dental treatment. You remain awake and can communicate with the dentist.

Children During Shorter Treatments

Nitrous oxide may be an option for some children who feel nervous about dental treatment. The dentist will first determine if it is suitable for the child and the procedure.

Patients with a Strong Gag Reflex

Nitrous oxide may help some patients who have a strong gag reflex during dental treatment. The dentist will assess whether it is appropriate for the appointment.

Longer or Complex Appointments

For some longer procedures, nitrous oxide may help patients remain relaxed and comfortable during treatment. Suitability depends on the procedure and the patient's health status.
