Answer 1

We have nerves in our teeth so;

1) We know when to stop biting (pressure), and

2) When we should intervene to pull out decaying teeth (pain).

Answer 2

Partly they’re leftover from when your teeth were growing, and partly it helps you know if something is wrong with your tooth.

Answer 3

One thing I didn’t see mentioned: the nerves in your mouth/teeth play a big role in your ability to form words and speak.
