Sedation dentistry refers to the use of sedation during dental treatment. Sedation is most commonly used during extensive procedures, for patients with dental fear, 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 (INTUBATION).

Patients with dental fear, low pain tolerance, major dental treatment, physical handicaps or strong gag reflexes may require sedation. Procedures like fillings, crowns, bridges, root canals, extractions, cosmetic procedures and periodontal treatments often require sedation.

 
Laughing Gas

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 affect 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 ten 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.
