Nitrous oxide, also known as laughing gas, is a short acting gas used to ease dental anxiety. It has an almost instant effect and will quickly relax you. It can be used for almost any procedure, including cleanings, extractions, and fillings. Nitrous oxide is one of the earliest forms of sedation dentistry used by dentists. We will place a mask over your nose. The mask will push a mix of nitrous oxide and oxygen that quickly takes effect after several steady breaths. As soon as the mask is removed, the effects of the gas diminish immediately, and you will be able to walk without difficulty. Overall, it is a quick and easy way to relax the body and mind of someone with dental phobia.
