Dental anesthesia is the administration of sedative agents by a qualified provider in a dental environment with the purpose of enhancing patient comfort and facilitating dentist ease. Sedation or anesthesia is usually accomplished by intravenous (IV) medications. However, inhaled, intramuscular, and oral agents may also be utilized. In an office setting, a range of anesthesia levels can be administered, including mild sedation, moderate sedation, deep sedation and general anesthesia.
