"Just the Facts" About Dental Sedation

By Kevin R. Doring, DDS

The benefits of sedation dentistry are numerous. Many patients choose sedation to reduce or eliminate discomfort or anxiety that may be associated with some dental treatments. Sedation is commonly used during extensive procedures, such as implant placement or reconstruction “make-overs.” Patients who feel “dental phobic” (have a low pain tolerance, have physical handicaps or have strong gag reflexes) are relieved to know that with the option of sedation they can “go to sleep” while their dental procedures are completed.

When a patient chooses to be sedated for their dental procedures there are several options, which will achieve varying levels of “being asleep.”

Local anesthesiais administered by injecting medication into tissue or by applying a medication topically to an area to eliminate sensation. A local injection is typically administered for fillings, root canals and extractions.

Minimal sedationis used most frequently in dentistry and usually involves taking medications orally. All bodily functions remain normal and the person is able to breathe on his or her own. The patient may respond normally to verbal commands and may experience some degree of amnesia about what happened during their dental appointment. Nitrous oxide or “laughing gas” may be used to achieve minimal sedation and in combination with a recommended dosage of oral medication.

Moderate sedationis achieved by using medications that can be taken orally or intravenously (IV). Patients who undergo moderate sedation are awake and respond to touch and/or verbal commands. All bodily functions remain normal, and the patient does not need assistance breathing.

Deep sedationcan be achieved by injecting medication, giving oral medications, and in combination with gases. Patients who are deeply sedated are not easily awakened but may respond to some stimulation. Patients may need some breathing assistance at deeper levels.

Is It Safe?

Sedation is a safe way in which to have your dental work completed comfortably and stress free. You should talk to your dentist and gain a thorough understanding of how sedation works, what is appropriate for you, and what is expected of you before the procedure. Your medical history will be examined comprehensively to ensure safe sedation and your vital signs will be monitored throughout the entire procedure to confirm that your blood pressure, pulse rate, and blood oxygen levels are normal.
