Henry breaking policeman’s teeth (8)

I believe the answer is:

choppers

'teeth' is the definition.
(chopper is a kind of tooth)

'henry breaking policeman's' is the wordplay.
'henry' becomes 'h' ('H' can be a synonym of 'henry').
'breaking' is an insertion indicator.
'policeman's' becomes 'coppers' (copper is a kind of policeman).
'h' put inside 'coppers' is 'CHOPPERS'.

(Another definition for choppers that I've seen is " In slang, false teeth or helicopters".)

I've seen this clue in The Times.
