To ponder during brief lulls in eating on Thanksgiving: How do we detect small particles of food stuck in our teeth?

A) Nerves in the roots of teeth sense pressure changes that deviate from nominal

B) Nerves in the gum sense something non-nominal attached

C) Nerves in the tongue sense something, somewhere non-nominal, based on occasional sampling as the tongue moves around in the mouth

D) Combinations of the above

E) None of the above
