Study hesitatingly prepared for oral examiner? (6,9)

I believe the answer is:

dental hygienist

'oral examiner?' is the definition.
(person who examines mouths)

'study hesitatingly prepared' is the wordplay.
'study' becomes 'den' (term for a study or office).
'prepared' is an anagram indicator.
'hesitatingly' anagrammed gives 'talhygienist'.
'den'+'talhygienist'='DENTAL HYGIENIST'

'for' is the link.

I've seen this clue in The Times.
