Poor Dante finds fifth circle is like pulling teeth (6)
I believe the answer is:
dental
'is like pulling teeth' is the definition.
I can't tell whether this defines the answer.
'poor dante finds fifth circle' is the wordplay.
'poor' is an anagram indicator.
'finds' says to put letters next to each other.
'fifth circle' becomes 'l' (I can't justify this - if you can you should believe this answer much more).
'dante' anagrammed gives 'denta'.
'denta'+'l'='DENTAL'
Can you help me to learn more?
(Other definitions for dental that I've seen before include "Consonant" , "Concerning teeth" , "Relating to teeth" , "Concerned with teeth" , "concerned with choppers" .)
