Teach notion about food processor (6,5)

Ross

I believe the answer is:

canine tooth

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

'food processor' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'teach notion about' is the wordplay.
'about' is an anagram indicator.
'teach'+'notion'='teachnotion'
'teachnotion' is an anagram of 'CANINE TOOTH'.

Can you help me to learn more?

(Another definition for canine tooth that I've seen is " Sharp-pointed fang".)
