Nitrous oxide help patients overcome their fear of dentistry. It makes you calm and relaxed during procedures. Your dentist places a small mask over your nose and you are asked to take a few deep breaths. Oxygen will be administered at 100% for a few minutes and then nitrous oxide will be increased gradually. You might feel tingling in your arms and legs or get light-headed.

At the end, the mask will be removed.
