Dentist

A dentist was a medical practitioner specialising in the care of teeth. After eating a sweet, the First Doctor felt a pang of toothache. (TV: The Celestial Toymaker) When the TARDIS landed in Tombstone, Arizona in October 1881, he sought out a dentist and found the establishment of Doc Holliday. Seeing an opportunity to evade Seth Harper and the Clanton brothers, Holliday pulled the tooth for the Doctor and then dressed him with items that might be expected to adorn Holliday himself. Coupled with the Doctor's miscommunication, this fooled Harper into believing the Doctor was Holliday. (TV: The Gunfighters)
