Moral dilemma for tooth (5)
I believe the answer is:
molar
'tooth' is the definition.
(molar is a kind of tooth)
'moral dilemma' is the wordplay.
'moral' can be anagrammed to 'MOLAR'.
Though, I am not sure how the anagram is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for molar that I've seen before include "that could be capped" , "Moral (anag.)" , "Dealing with masses" , "Broad-crowned tooth" , "of ivory, perhaps" .)
