Dentist Who

Dentist Who is the long-running British science fiction franchise, made partially in response to the widely held belief that the British take poor care of their teeth.

The series involves The Dentist, a mysterious alien from the planet Gingivae who traverses time and space in his craft the TARTAR.  He is usually accompanied by one or more dental assistants, and often uses his Sonicare Screwdriver to help manipulate machinery.
