Semi-Painless Dentistry

History
The Semi-Painless Dentistry is a dentist seen in the opening sequence during The Simpsons season 1. It was later replaced with Candy Most Dandy in seasons 2 and beyond. Very little is known as it is never seen beyond the opening sequences. However, during Last Exit to Springfield Lisa has a check-up at Painless Dentistry. Furthermore, the sign reads: "Painless Dentistry Formerly Painful Dentistry". Since the titles are so very similar, it is possible that the two shops are the same, but just with a different name, or a direct competitor.
