Garden taken from the dentist (4)
I believe the answer is:
eden
'garden' is the definition.
(Garden of Eden in the Bible)
'from the dentist' is the wordplay.
'from' says the answer is hidden in the clue.
'EDEN' can be found hidden inside 'the dentist'.
'taken' acts as a link.
(Other definitions for eden that I've seen before include "Paradisal garden" , "Adam and Eve home" , "late PM" , "Tory Prime Minister, 1955-57" , "Paradise - ex-PM" .)
