Anesthesia for Oral Surgery Procedures
Several methods of anesthesia are available. The method of anesthesia that is chosen for or by a patient depends upon the nature of the surgical procedure and the patient’s level of apprehension. The following table illustrates the choices of anesthesia, a description of the anesthetic technique, and the usual indications for that technique.
The patient remains totally conscious throughout the procedure. A local anesthetic (e.g. lidocaine) is administered (injected) in the area where the surgery is to be performed. Local anesthetic is used in conjunction with the other methods of anesthesia in all oral surgery procedures.
Simple oral surgery procedures such as minor soft tissue procedures and basic tooth extractions may be done under local anesthesia.
Nitrous Oxide Sedation with Local Anesthetic:
A mixture of nitrous oxide (laughing gas) and oxygen is administered through a nasal breathing apparatus. The patient remains conscious in a relaxed condition. Nitrous oxide has a sedative and analgesic (pain- controlling) effect.
Simple oral surgery procedures to more involved procedures such as removal of wisdom teeth and placement of dental implants may be performed using nitrous oxide sedation.
Office Based Intravenous Anesthesia with Local Anesthetic:
Medications are administered through an intravenous line (I.V.). The patient falls asleep and is completely unaware of the procedure being performed. Medications most commonly used are Fentanyl (opiate), Versed (benzodiazepine), Ketamine, and Diprivan. Supplemental oxygen is delivered through a nasal breathing apparatus and the patient’s vital signs are closely monitored.
Intravenous anesthesia includes I.V. sedation and general anesthesia for all types of oral surgery. A patient may choose intravenous anesthesia for simple procedures depending on their level of anxiety. Most people having their wisdom teeth removed or having a dental implant placed will choose intravenous anesthesia. General anesthesia and/or I.V. sedation may be necessary if local anesthesia fails to anesthetize the surgical site which often occurs in the presence of infection.
Extensive Training and Experience in the Control of Pain and Anxiety
The ability to provide patients with safe, effective outpatient anesthesia has distinguished the specialty of oral and maxillofacial surgery since its earliest days. As the surgical specialists of the dental profession, Oral and Maxillofacial Surgeons are trained in all aspects of anesthesia administration. Following dental school, Oral and Maxillofacial Surgeons complete at least four years of training in a hospital-based surgical residency program alongside medical residents in general surgery, anesthesia and other specialties. During this time, OMS residents must complete a rotation on the medical anesthesiology service, during which they become competent in evaluating patients for anesthesia, delivering the anesthetic and monitoring post-anesthetic patients.
As a result of this extensive training, Oral and Maxillofacial Surgeons are well-prepared to identify, diagnose and assess the source of pain and anxiety within the scope of their discipline, and to appropriately administer local anesthesia, all forms of sedation and general anesthesia. Further, they are experienced in airway management, endotracheal intubation, establishing and maintaining intravenous lines, and managing complications and emergencies that may arise during the administration of anesthesia.
Putting Your Mind at Ease
The best way to reduce anxiety is to make certain you know what to expect during and after surgery. As with most anxiety-producing situations, the more you know, the less you have to be anxious about. Prior to surgery, your Oral and Maxillofacial Surgeon will review with you the type of anesthetic to be used, as well as the way you’re likely to feel during and after the operation.This is the time to discuss any concerns you may have about any facet of the operation.
During surgery, one or more of the following may be used to control your pain and anxiety: local anesthesia, nitrous oxide-oxygen, intravenous sedation and general anesthesia. Commonly, patients describe their feelings during surgery as comfortable and surprisingly pleasant.
After surgery, you may be prescribed a medication to make you as comfortable as possible when you get home.

The American Association of Oral and Maxillofacial Surgeons (AAOMS), the professional organization representing more than 9,000 oral and maxillofacial surgeons in the United States, supports its members’ ability to practice their specialty through education, research and advocacy. AAOMS members comply with rigorous continuing education requirements and submit to periodic office examinations, ensuring the public that all office procedures and personnel meet stringent national standards.
