Local Anesthesia is the elimination of pain sensation in one part of the body by topical or regional injection of a drug without loss of consciousness.
General Anesthesia is a controlled state of unconsciousness during which patients are not aroused by painful stimulation and the ability to independently maintain ventilation is impaired. Patients often require assistance in maintaining airway.
Certain types of anesthesia are covered by medical insurance rather than your dental benefit. Ask your dentist for more information.
