Presidential Candidate Dr. Ben Carson -- My Latest Speech Lacks Teeth

Presidential candidate Dr. Ben Carson does not lack wisdom, but incisors are a different story.

The Republican hopeful -- who made a name for himself in 1987 as the first neurosurgeon to separate twins conjoined at the head -- was stumping at Tommy's Country Ham House in Greenville, South Carolina where he chowed down on scrambled eggs, grits and ham biscuits when he noticed a bonus on his plate ... his front tooth had fallen out.

The good doc stared into his plate, thought for a second then discretely placed the errant chomper into his shirt pocket.

Carson then stood up and delivered an impassioned speech ... with a hint of whistle.
