Nuttin' but the Tooth (Final Destination Version)

Tim Carpenter is a patient of Sam Lawton the dentist. Tim is obviously nervous, but he doesn't seem to mind that Sam is reading a dentistry instruction book prior to performing (as well as during) Tim's checkup. As Tim's mouth opens wide, Sam comes across a discolored, rotten tooth (or cavity) that needs to be removed.

After poking the rotten tooth several times with a probe and also improperly injecting Novocain into Tim's mouth, Sam tries to drill out the tooth. When Sam is drilling, the drill's battery goes dead, much to his disappointment. However, after Sam managed to get a another battery, he attempted several times to place the battery in the drill. Unfortunately, he only succeeds in drilling a hole in the back of Tim's throat. Next, Sam tries the old fashioned method of tying one end of a string around Tim's tooth, and the other end to a doorknob. Sam rings a doorbell, and Alex Browning (who is in the middle of shaving) answers the door, causing Tim's jaw to get ripped from his head. Tim's rotten tooth is one of only a few teeth that aren't torn out due to this attempt. Before the episode ends, however, the rotten tooth falls out on its own, finally completing the operation.
