A couple of toothy tales

Dave Langford lists a couple of stories where "Earth's dentists are so superior that they get abducted by aliens desperate for their skills", in SFX, February 2012.

1. Avram Davidson's "Help! I am Dr Morris Goldpepper": "held captive by toothless humanoids within whose dentures he conceals his message for help."
2. "The dentist hero of Piers Anthony's Prostho Plus is also kidnapped & forced to cruise the galaxy fixing weird sets of teeth".
