In dentist, as terrified, have trying experience? (5)
I believe the answer is:
taste
'trying experience?' is the definition.
(I've seen this in another clue)
'in dentist as terrified' is the wordplay.
'in' indicates a hidden word.
'TASTE' is hidden within 'dentist as terrified'.
'have' is the link.
(Other definitions for taste that I've seen before include "One of the senses" , "Artistic appreciation" , "Try (food)" , "to eat in small amounts" , "Judgment" .)
