If the thought of seeing your dentist gives you chills every six months, an anesthetic may be the solution. Sedation dentistry uses a combination of techniques, ranging from nitrous oxide or "laughing gas" to general anesthesia, to relax a patient during surgeries or otherwise uncomfortable appointments. For even the most severe dental phobias, there is no longer a reason to avoid the dentist altogether.
A Guide To Sedation Dentistry
The dental office has long been the most common setting for routine dental procedures that use sedation and anti-anxiety techniques. These techniques can be used for any type of dental procedure depending on the needs of the patient. Ultimately, your fears and phobias can be managed so that you can receive the dental care you require no matter where the treatment takes place.
Your overall health, as well as physical and mental conditions you may be battling at the time, are important to be able to safely undergo certain types of sedation – especially in the dental office. Certain of these conditions may require clearance from a physician: cardiac disease, hypertension, diabetes and respiratory diseases should all be addressed prior to a given type of sedation. Your dentist will take a thorough medical history and physical assessment before proceeding, and if need be, recommend a product like Colgate® Total® Advanced Deep Clean to get home care on the right track. He or she may also ask you to receive medical clearance from your physician.
Probably the most common form of sedation in the dental office is nitrous oxide, or "laughing gas." Also called inhalation analgesia – and used to alleviate pain when giving birth, according to the National Institutes of Health (NIH) – nitrous oxide does not put you to sleep, and is effective at reducing your anxiety about a dental procedure. It is very safe and provided in most dental offices. Local injections of anesthesia, which are still used in combination with nitrous oxide, now see consistent effectiveness, and some are practically painless. Nonetheless, the gas can be administered by a machine to further reduce the discomfort of the injection.
The next type of sedation comes in the form of a pill or liquid that you take orally. This is called enteral sedation. Like local anesthetics, oftentimes it is used in combination with nitrous oxide. You may still be awake, but not nervous about the dental work.
Intravaneous (IV) sedation is another common method of anti-anxiety wherein the sedative is directly injected to a vein. This technique will allow the dentist to provide a deeper sedation, although you will still be awake but less aware of the procedure. The process requires recovery time after you leave the office.
General anesthesia is a form of sedation by which you will be asleep for the entire procedure. It is practiced using drugs that are directly injected into a vein, along with the possible inhalation of a gaseous anesthetic. A thorough recovery time in the office may be required before leaving.
Although most dentists are qualified to administer nitrous oxide, other types of sedation require additional training, equipment and emergency supplies. And because the vast majority of the U.S. requires that the dentist have a sedation license to perform these techniques, not every office will provide the service you'd like. For this reason, some may choose to contract qualified physicians or dentists to come to their office to perform sedation for their patients.
The American Dental Association (ADA) outlines a set of guidelines for providing sedation and the training required. The board of dentistry in your state will determine the type of license required by your dentist. At the end of the day, sedation dentistry can keep fear from making you forgo the smile you desire.
