Imagine undergoing a complex dental treatment like a root canal, extraction, or oral surgery. When your treatment is complete, you have no recollection of the time it took, the pain, the noise, or the discomfort you were expecting. Sedation dentistry uses medication to help patients relax during dental procedures. It’s sometimes referred to as “sleep dentistry,” although that’s not entirely accurate. Patients are usually awake with the exception of those who are under general anesthesia.
