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

'apart so sought medical help' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'detect worn tooth break' is the wordplay.
'break' is an anagram indicator.
'detect'+'worn'+'tooth'='detectworntooth'
'detectworntooth' with letters rearranged gives 'WENT TO THE DOCTOR'.
