The Dentist

The dentist pulls out a Novocain needle to give the man a shot, so he can extract the man's tooth. 'No way! No needles. I hate needles' the patient said.
The dentist starts to hook up the nitrous oxide and the man objects I can't do the gas thing. The thought of having the gas mask on is suffocating to me! The dentist then asks the patient if he has any objection to taking a pill. 'No objection,' the patient says. 'I'm fine with pills.'
The dentist then returns and says, Here's a Viagra tablet.'
The patient says, 'Wow! I didn't know Viagra worked as a pain killer!'
It doesn't' said the dentist, 'but it's going to give you something to hold on to when I pull your tooth.

First U.S. patent for artificial teeth

In 1822, Charles M. Graham of N.Y. was issued the first U.S. patent for artificial teeth. The record, and its details, was lost in the Patent Office fire of 15 Dec 1836. Similarly lost, the patent by William R. Eagleson for setting natural and artificial teeth (4 Oct 1817). False teeth had been used since Colonial years, with various attempts to replace rotten teeth, which were extraacted to avoid illness. George Washington had at least four sets of false teeth (though none were wooden, despite a myth to that effect). His first dentures were made using human teeth set into carved ivory. In 1789, dentist John Greenwood of New York, made Washington a complete set from hippopotamus ivory, gold wire springs and brass screws holding human teeth. His one natural remaining tooth was a molar, and a hole was left for it.«[Image: Closeup of George Washington's dentures (c.1790) with human teeth and modeled teeth carved from cow teeth and elephant ivory.]
