Nitrous Oxide Sedation Dentistry

Sedation dentistry Louisville

One of the most commonly used methods of relieving a patient’s dental anxiety is nitrous oxide sedation dentistry, also known as inhalation sedation. Over one-third of dental professionals utilize nitrous oxide, commonly referred to as “laughing gas”, to effectively treat patients with dental fears and phobias.


Nitrous oxide is the mildest form of dental sedation where patients retain their reflexes and can respond normally to stimulation and verbal commands. Nitrous oxide is used in sedation dentistry because of its combined benefits as both a sedative and anti-anxiety agent. Nitrous oxide has a very rapid effect, usually taking effect within several minutes after it is inhaled.

Nitrous oxide also raises your pain tolerance by suppressing the signals to the brain. It is often termed “laughing gas” because it produces a euphoric feeling that alleviates anxiety and fears and often makes you want to laugh. Nitrous oxide sedation works well for patients with mild to moderate anxiety who are undergoing light procedures or routine visits to the dentist. This method of sedation has very few side effects, recovery time is quick, and you will be able to resume normal activities immediately.


Nitrous oxide sedation is considered the safest method of sedation dentistry for most people. Patients who benefit from inhalation sedation include anyone with mild dental anxiety, children who are uncooperative or fearful of the dentist, or patients with special needs or hyperactive gag reflexes. Virtually any patient who wants to feel more relaxed and comfortable during dental treatments would enjoy the advantages of inhalation sedation.
