Happy Gas at the dentist
Happy gas, also called laughing gas or nitrous oxide, is a mild form of sedation you breathe in through a small mask over your nose. It can help you feel calmer and more relaxed during dental treatment, while you stay awake. Happy gas is given by your dentist and usually wears off soon after the mask is removed. Your dentist checks whether it’s suitable for you before your appointment.
Sedation is a medical procedure and carries risks. Not everyone is suitable. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner. Read about treatment risks.
What is happy gas?
Happy gas is nitrous oxide mixed with oxygen. You breathe it in through a small, soft mask that sits over your nose.
You might hear it called happy gas, laughing gas or nitrous oxide. They’re all the same thing. Despite the name, most people feel calm rather than giggly.
Happy gas is usually used alongside local anaesthetic, which numbs the area being treated. The gas helps you feel more relaxed, and the local anaesthetic manages the feeling in your tooth.
Your dentist adjusts the amount during your appointment and stays with you the whole time.
