Let's start in China, where a shaky old man can perform dentistry next to a rock outcropping for you to beat your skull against when the pain becomes too unbearable.

And nothing says 'sanitary' like this Bangladeshi dentist's office. Not only is there no such thing as laughing gas in that snake-infested mud pit of a country, thjere's no such thing as laughter.

Remember this next time your dentist turns up his water pick a little too high for you comfort.

And be thankful that he doesn't need to handcuff you to a dead stump to keep you from fleeing his office and the soul-crushing amount of pain that lives there.

Oh, I see. You have a sharp piece of gravel from the floor of my office stuck in your teeth! If a man doesn't even know what teeth look like well enough to draw them (http://madbe.net/wp-content/uploads/2007/10/009_dantist_56.jpg), do you really want him operating on yours? Okay, now to really make you wince, watch this video (http://www.youtube.com/watch?v=QcfEuzR2v0s) about how dentistry is done in Slovenia. I hope I've disturbed you, and made you feel my anguish. Now I'm off to the oral surgeon. Thanks God for Internet, laughing gas and Vicodin...
