Sedation dentistry refers to the use of sedation during dental treatment. Sedation dentistry is most commonly used during extensive procedures, for patients with dental phobia or for patients who find it difficult to sit still. There are different types of sedation, including nitrous oxide (“laughing gas”), IV sedation, oral sedatives and general anesthetic.
Sedation dentistry is perfect for patients who may not be up to the experience of dental treatment. If you have a phobia or strong gag reflex, or a medical condition that prevents sitting still, sedation can be the solution. Sedatives will calm or relax a patient during treatment, even if a patient remains conscious.
Sedation medications can be oral or used as a gas or injectable. Whichever sedation type is chosen depends on the patient’s desire to be fully awake or fully asleep. It can be used for any procedure, but is most commonly employed when patients receive crowns, bridges, root canals, periodontal treatment, tooth extractions, or implants and fillings.
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.
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. Because it is a mild sedative, patients are still conscious and can talk to their dentist during their visit. After treatment, the nitrous is turned off and oxygen is administered for five to 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. Your doctor will provide you with pre- and post-sedation instructions.
