After shopping at amazon.com is that there seems to be an underground group of people who either do dental procedures on themselves or others. If you choose an arbitrary item related to "fixing" a tooth, etc. then look at all the "Customers Who Bought This Item Also Bought" items you will notice, as you do this several times, that people are buying stuff like professional dental equipment and supplies. For example, take a look at this item... I can't get the image of someone drilling a tooth in the back room of some hot, dusty warehouse in some strip mall on Main Street, USA. Gotta love our Healthcare system! And who says it needs to change? Jan P.S. Someone (like 60 Minutes) should do a story on this and maybe even find and interview people who do this.
