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.
MethodTypes of AnesthesiaDescription of TechniqueUsual Indications
Method Local AnestheticDescription of Technique The patient remains totally conscious throughout the procedure. A local anesthetic (e.g. lidocaine) is administered 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.Usual Indications Simple oral surgery procedures such as minor soft tissue procedures and simple tooth extractions.
Method Nitrous Oxide Sedation with Local AnestheticDescription of Technique 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.Usual Indications Simple oral surgery procedures to more involved procedures such as removal of wisdom teeth and placement of dental implants.
Method Office Based General Anesthesia with Local Anesthetic*Description of Technique 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.Usual Indications General anesthesia is available for all types of oral surgery. A patient may choose general 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 general anesthesia. General anesthesia may be necessary if local anesthesia fails to anesthetize the surgical site which often occurs in the presence of infection.
Method Hospital or Surgery Center Based General AnesthesiaDescription of Technique A patient is admitted to a hospital or surgery center where anesthesia is administered by an anesthesiologist.Usual Indications Indicated for patients undergoing extensive procedures such as face and jaw reconstruction and TMJ surgery. Also indicated for patients with medical conditions such as heart disease or lung disease who require general anesthesia.
Intravenous Sedation (“Twilight Sedation”)
Our office offers our patients the option of Intravenous Sedation or Dental Intravenous Anesthesia or to some it is referred to as “Twilight Sedation” for their dental treatment. Intravenous Sedation or “twilight sleep” helps you to be comfortable and calm when undergoing dental procedures. Your treatment can be completed under intravenous sedation. Intravenous sedation or “IV sedation” (twilight sedation) is designed to better enable you to undergo your dental procedures while you are very relaxed; it will enable you to tolerate as well as not remember those procedures that may be very uncomfortable for you. IV sedation will essentially help alleviate the anxiety associated with your treatment. You may not always be asleep but you will be comfortable, calm and relaxed, drifting in and out of sleep – a “twilight sleep”.
If you choose the option of intravenous sedation your IV sedation/anesthesia is administered and monitored by the doctor therefore eliminating the costly expense of having your treatment carried out in an operating room or same day surgical facility.
Nitrous Oxide (Laughing Gas)
Nitrous Oxide is a sweet smelling, non irritating, colorless gas which you can breathe. Nitrous Oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe; the patient receives 50-70% oxygen with no less than 30% nitrous oxide. Patients are able to breathe on their own and remain in control of all bodily functions. The patient may experience mild amnesia and may fall asleep not remembering all of what happened during their appointment.
