Sedation dentistry is used to provide a relaxing and anxiety-free experience for certain people receiving dental treatment. It enables individuals too afraid to go to the dentist to receive the dental care they need while avoiding the common apprehension known as dental phobia.
Sedation is a process used to establish a relaxed, easy and calm state through the use of sedatives. Sedative drugs (tranquilizers, depressants, anti-anxiety medications, nitrous oxide, etc.) can be administered in a variety of ways. In the past, intravenous (IV) sedation – sedatives delivered via injection into the blood vessels of the hand or arm – was predominantly used to sedate a dental patient.
Oral sedation dentistry is now the most common technique used in the United States and Canada to quell patient fears. The technique is easy and requires no needles. Best of all, the medications create such a comfortable experience that most patients do not remember the visit; it is as if they slept through the treatment. In reality, oral sedation dentistry maintains a level of consciousness in the patient for safety and cooperation. Although some forms of sedation (such as nitrous oxide gas) may raise your threshold for pain, most dental treatments still require a local anesthetic injected in the mouth, even when sedation dentistry techniques are performed.
This local anesthetic will temporarily block pain impulses from the affected teeth and gum tissue. However, this injection will occur after you are already sedated and comfortable, so most likely you won't be bothered by or remember the sensation of having the injection.
Regardless of the type of sedation dentistry you receive, it is important to have a responsible caregiver accompany you to the procedure (and drive you there if you must take oral medication before arriving for your appointment). The caregiver should drive you home after the procedure is complete and stay with you for an additional two to four hours at home.
