Tooth, incorporated, is gold (7)

I believe the answer is:

incisor

'tooth' is the definition.
(I know that incisor is a type of tooth)

'incorporated is gold' is the wordplay.
'incorporated' becomes 'inc'.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'inc'+'is'+'or'='INCISOR'

(Other definitions for incisor that I've seen before include "Canine" , "Type of tooth" , "Ivory perhaps" , "One takes a bite" , "carnivore requires?" .)

I've seen this clue in The Daily Express.
