Nitrous Oxide (N2O) Sedation Dentistry in Baltimore, MD

Stress-free dentistry is here in The Village of Cross Keys! Nitrous Oxide (N2O) is for dental patients who have heightened anxiety when visiting the dentist. N2O is a non-allergenic, non-irritating gas that has no color or smell. By simply breathing the Nitrous Oxide, patients with anxiety will relax and feel less discomfort. It is one of the safest forms of sedation available. Patients are able to safely drive themselves home or to work at the end of their appointment. Most patients begin to feel the N2O take effect within 3 – 5 minutes and following treatment, the effects of this gas are completely reversed within 3 – 5 minutes of discontinuing gas, by simply breathing normally.

Don’t avoid the dentist. Let our The Village of Cross Keys doctors take care of your dental needs with stress-free N2O sedation.
