What is the position of teeth for the affricates?
Affricates
This seems to be a strange question, since one doesn't normally think of teeth as articulators which can take different positions. When describing a sound it would be more appropriate to speak of the position of the tongue, the lips, the soft palate and the jaw.
That being said, affricates have a variety of places of articulation. In English, /tS/ and /dZ/ are postalveolar, somewhere between the alveolar ridge and the hard palate.
