Nitrous Oxide (Laughing Gas)

Nitrous oxide, often called laughing gas, is a mild sedative breathed in through a small nose mask. It takes effect quickly and wears off shortly after the gas is stopped, so most patients can drive themselves home after their appointment.

It is commonly used to ease dental anxiety, reduce gag reflex sensitivity, and make longer or more involved procedures feel more manageable.

Nitrous oxide can be a good option if you feel nervous about dental visits, have a sensitive gag reflex, or simply prefer a calmer experience during treatment. Whether it suits you depends on your medical history, which the dentist reviews before recommending sedation.

• Patients with mild to moderate dental anxiety
• Patients who tense up during injections or longer appointments
• Patients with a strong gag reflex during impressions or x-rays

A soft nose mask is placed and the mix of nitrous oxide and oxygen is adjusted to a comfortable level. You stay awake, able to respond, and aware of your surroundings. When treatment is finished, you breathe pure oxygen for a few minutes so the effects clear quickly.

Nitrous oxide works alongside the office's other patient comfort techniques, like clear explanations and breaks when you need them.
