Nitrous Oxide

For some patients, visiting the dentist can cause nervousness or anxiety. Fear of instruments, needles, sounds, or concerns about discomfort can make it difficult to feel relaxed during treatment.

‍

Nitrous oxide sedation, commonly known as laughing gas, is one option that can help eligible patients feel calmer during dental procedures. It is inhaled through a small mask placed over the nose and can help you feel relaxed while you remain awake and able to communicate with your dental team at MacArthur Dental Arts in Irvine, CA.

‍

What Is Nitrous Oxide Sedation?

‍

Nitrous oxide is a colorless, odorless gas mixed with oxygen and inhaled through a nasal mask. Despite the nickname "laughing gas," not everyone becomes giggly, patients commonly describe feeling calm, relaxed, or slightly lightheaded. Nitrous oxide is a sedation technique, not a general anesthetic, so patients typically remain conscious, responsive, and able to communicate throughout treatment.

How Nitrous Oxide Can Help With Dental Anxiety

‍

• Feel nervous about visiting the dentist
• Have a strong fear of dental procedures
• Become anxious about needles or dental instruments
• Have difficulty relaxing in the dental chair
• Have a sensitive gag reflex
• Need help staying calm during treatment

‍

Your dentist will discuss your concerns and medical history to determine whether nitrous oxide is appropriate for you.

‍

What to Expect During Treatment

‍

Before sedation, your dental team reviews your health history, medications, and allergies. A small nasal mask is then placed to deliver a controlled mixture of nitrous oxide and oxygen. The effects begin quickly, often bringing a feeling of relaxation, warmth, or mild tingling, and you remain conscious and able to respond throughout your procedure. At the end of treatment, the nitrous oxide is stopped and oxygen is administered until the effects wear off, which typically happens rapidly.
