Sedation dentistry refers to the use of sedation during dental treatment. Sedation is most commonly used during extensive procedures, for patients with dental phobia or for patients who find it difficult to sit still. Sedation is endorsed by the American Dental Association and is an effective way to make many patients comfortable during their dental visit.

Before using a sedative or anesthetic, it is important to tell your dentist about any medications or medical treatments you are receiving. Before administering any sedative or anesthetic, your dentist will talk to you about the process of sedation and pre-and post-sedation instructions.

Types of Sedation

Nitrous Oxide Sedation

Nitrous oxide, more commonly known as "laughing gas," is often used as a conscious sedative during a dental visit. The gas is administered with a mixture of oxygen and has a calming effect that helps phobic or anxious patients relax during their dental treatment. After treatment, the nitrous is turned off and oxygen is administered for 5-10 minutes to help flush any remaining gas. The effects wear off almost immediately. Nitrous oxide rarely has side effects, although some patients may experience minor nausea and constipation.

General Anesthesia

General anesthesia puts a patient completely to sleep during a dental procedure. The anesthesia can be administered in a variety of ways, including injection, gas inhalation or through an IV, depending on the circumstances. Aside from keeping the patient unconscious, the sedation also acts as an amnesiac, causing the patient to forget the events immediately before and after the procedure. General anesthesia is very safe under trained supervision.
