Deposit on the teeth (6)

I believe the answer is:

tartar

'deposit on the teeth' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for tartar that I've seen before include "Dental deposit" , "Unpleasant sort" , "For instance, Genghis Khan" , "Hard, crusty deposit on the teeth" , "saucy stuff" .)

I've seen this clue in the Evening Standard and The Mirror.
