Nitrous Oxide

Dentist in Towson, MD

Nitrous Oxide is a chemical compound with the formula N2O. At room temperature, it is a non-flammable, colorless gas with a slightly sweet odor and taste. It is used in dentistry as inhalation sedation, given its analgesic effects. It is commonly referred to as ‘laughing gas’ due to the euphoric effects of inhaling it. At Ousborne and Keller we offer Nitrous Oxide, in conjunction with local anesthetic, at patient request to reduce dental anxiety.

Nitrous Oxide is very safe. It has very few side effects and has no ill effects on the heart, lungs, kidney, liver or brain. Nitrous Oxide works very rapidly and has no ‘hangover’ effect since the gas is eliminated from the body within three to five minutes after the gas supply is stopped. This allows patients to drive home safely and no escort is needed as would be with Oral Conscious Sedation.

At Ousborne and Keller our goal is to offer the most comfortable dental experience possible and the utilization of Nitrous Oxide at patient request allows us to do so without compromising our patients overall health and wellness.
