President Hoover went to the Walter Reed Military Hospital in Washington for dental treatment, and it was found necessary to extract three or four of his teeth. An orderly who was in attendance had the bright idea that there were people who would be willing to pay good money for a President’s teeth, so he gathered them up as soon as Mr. Hoover had left. He not only possessed himself of the Hoover teeth, he also collected all the teeth that had been extracted that day from the jaws of many sufferers by the hospital dentists. The exact number of his collection is not stated, but it was considerable and he had no difficulty in disposing of them all as genuine Hoover teeth at 50 cents. This price he found afterwards was absurdly low, for within a day or two he discovered that they were being sold in the city at several dollars each. Then somebody discovered that there were more teeth on offer than the Hoover household could have supplied, even if every member had visited the dentist and had every tooth extracted. Quotations in the Presidential old teeth market immediately dropped to zero.
