Nitrous oxide is a safe and effective sedative agent that is mixed with oxygen and inhaled through a small mask that fits over your nose to help you relax.
Nitrous oxide, sometimes called “laughing gas,” is one option your dentist may offer to help make you more comfortable during certain procedures. It is not intended to put you to sleep. You can still respond to your dentist’s requests and answer questions. Your dentist will ask you to breathe normally through your nose, and within a few short minutes you should start to feel the effects of the nitrous oxide.
Use of Nitrous oxide provides safe, comfortable dental treatment for patients with dental fear, anxiety or nervousness. Nitrous oxide is safe for children, but not all children will be able to receive it. Children must be able to put up with having the soft nose piece or mask placed over the nose. They also must be able to breathe through the nose, and follow instructions from the dentist.
Your dentist may want to talk to your medical doctor before giving you nitrous oxide if child has certain conditions.
