Comb parts (5)
I believe the answer is:
teeth
'comb parts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for teeth that I've seen before include "Real effectiveness" , "Being in your face" , "Incisors maybe" , "Eg, canines, incisors" , "Molars, incisors, etc" .)
