Gentle sedation for a calmer, more comfortable dental visit.
What to know
Laughing Gas (Nitrous Oxide), explained.
What it is, how it works and how it helps, in plain words.
Nitrous oxide, commonly called laughing gas, is a mild sedative you breathe in through a small mask over your nose. It helps you feel calm and relaxed while staying awake and able to respond.
Nitrous oxide is mixed with oxygen and breathed in throughout your procedure, and its effects begin within a few minutes. Your dentist can adjust the level as needed, and when treatment is done you breathe pure oxygen for a few minutes to clear the gas.
Laughing gas takes the edge off anxiety and can help calm a sensitive gag reflex, making routine treatment easier for both children and adults. Because it wears off quickly, most adults can return to their normal activities after the appointment.
