I'm a little stuck... Click here to teach me more about this clue!

'artistic dentist did?' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'what the' is the wordplay.
I cannot really see how this works, but
an anagram of 'the' is 'eth' which is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
