Also some trimming is the solution for one with the most prominent dentures (9)
I believe the answer is:
toothiest
'also some trimming is the solution for one with the most prominent dentures' is the definition.
I can't judge whether this definition defines the answer.
'also some trimming is the solution for one' is the wordplay.
I cannot quite understand how this works, but
'also' could be 'too' (synonyms) and 'too' is found within the answer.
'one' could be 'i' (roman numeral) and 'i' is present in the answer.
'is the' could be 'the' and 'the' is present in the leftover letters.
The remaining letters 'st' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
