Conscious sedation dentistry is a technique used to help patients relax during dental procedures. It involves the use of one or more drugs to produce a state of depression in the central nervous system (CNS) that allows treatment to be carried out, while maintaining verbal contact with the patient throughout the period of sedation. This type of sedation has minimal side effects, such as drowsiness, dry mouth, headache, and confusion or memory loss during the dental procedure. However, there are some risks associated with conscious sedation dentistry that should be taken into consideration.
The drugs and techniques used to provide conscious sedation for dental treatment must have a wide enough margin of safety that loss of consciousness is unlikely. Conscious sedation conserves the patient's ability to maintain a permeable airway independently and continuously. Intravenous sedation can cause breathing difficulty, as in people who have been sedated too deeply. This is rare, but it is important to be aware of this risk.
A good dentist will monitor breathing difficulty and other health problems during the procedure and while sedation is being administered. There is also a risk of receiving anesthesia, but it is generally safe when administered by experienced dentists. Certain people, such as those who are obese or those who have obstructive sleep apnea, should talk to their doctor before receiving sedation as they are more likely to develop complications from anesthesia. Oral sedation, also known as pill sedation, is one of three methods of sedation that dentists use to help calm patients during dental procedures. Unlike nitrous oxide sedation and intravenous (IV) sedation, patients take the sedative in pill form in the hours before the appointment.
An oral sedative is a type of benzodiazepine (that is, Valium, Halcion, Xanax), which decreases activity in the parts of the brain that control fear and anxiety. The result is a very relaxed and calm state of mind that will allow your dentist to do what they are supposed to do effectively. Fear of the dentist is very common and can be difficult to manage. Sedation dentistry helps fearful patients relax during cleanings and dental procedures so that they don't compromise their oral health. If you think that intravenous dental sedation is what you need, make sure you know the benefits and risks associated with it.
It's important to make sure that your dentist is trained and qualified to administer the type of sedation you will receive. Intravenous sedation works well for patients with severe dental anxiety, who need stronger sedation than nitrous oxide. However, only a small percentage of dentists who have completed the Dental Accreditation Commission (CODA) deep sedation and general anesthesia program can use these more complex techniques. Intravenous sedation quickly relieves nervousness, as anti-anxiety medication reaches the bloodstream directly. Oral sedation allows you to control your anxiety, but you get local anesthesia in your mouth without realizing how the injection feels because it's given after you're completely relaxed.
Mild to moderate sedation helps you stay relaxed and comfortable before and during the dental procedure. Dentists receive 20 to 25 hours of training on conscious oral sedation, keeping you awake during dental treatment for greater safety and cooperation. Some dentists use an anesthesiologist, who is specially trained to administer all levels of sedation and anesthesia to both children and adults. Sedation is most appropriate for people who have real fear or anxiety that prevents them from going to the dentist. Conscious sedation is a technique intended to treat dental phobia and should not be considered an alternative to effective local anesthesia or good behavioral management.
The importance of having properly trained personnel in an area properly equipped with monitoring tools cannot be overemphasized, along with the importance of a detailed evaluation before sedation. For emergency procedures where fasting cannot be guaranteed, the benefits of treatment and the risk of lighter and more effective sedation can be discussed.
