Generally, you will be given a prescription for a pill to take before your appointment. Since this is a sedative medication, you will need a companion to drive you to the appointment. Once you arrive, Dr. Knuth and his staff will begin monitoring your vital signs, including heart rate and blood pressure, to make sure that you stay completely safe through the procedure. He will then assess your level of sedation, and ask how you feel.
In some circumstances, Dr. Knuth may use more medication, but often this is not necessary. The dentistry will all be performed while you are relaxed and comfortable. When it is safe for you to move about, your companion will take you home, and then you will rest comfortably for the rest of the day.
