Nitrous Oxide

Nitrous oxide, commonly called “laughing gas,” is used as a mild dental sedation method to reduce anxiety and promote relaxation during periodontal and dental treatments.

Nitrous oxide is inhaled through a small mask over the nose, mixing with oxygen to produce conscious sedation — helping patients feel calm and comfortable while remaining awake.

Yes — when administered by trained dental professionals following safety protocols, nitrous oxide sedation is considered a safe and effective option for managing dental anxiety and pain.

No. Nitrous oxide provides conscious sedation, meaning you stay awake and responsive, but feel relaxed and less aware of discomfort.

Nitrous oxide works rapidly — effects are usually felt within minutes of inhalation and wear off quickly once the gas flow is stopped.

Some patients may experience mild effects such as light‑headedness or tingling, but these typically resolve quickly after the gas is discontinued. Your dentist will monitor your comfort throughout.

Patients with dental anxiety, sensitive gag reflex, or fear of dental treatment often benefit from nitrous oxide. A dental professional will determine if it’s the right sedation option for you.

Certain medical conditions or pregnancy (especially first trimester) may require alternative sedation options. Your dentist will review your health history before recommending nitrous oxide.

Nitrous oxide is suitable for many procedures to help ease anxiety, but its use depends on the treatment type and your individual needs — your dental team will advise what’s best.

While nitrous oxide primarily reduces anxiety and stress, it can also help increase comfort by diminishing pain sensitivity when combined with local anesthetic techniques as needed.
