How does dental anesthetic work to make us not feel pain?

Question

Why does dental pain hurt so much worse than any other kind of pain?

And how does local anesthetic make it so that we don’t feel pain on our teeth?

Answer 1

1 – teeth are in your head right next to your brain, so it’s harder to ignore 

2 – there are two types of dental anesthesia: nerve block and infiltration. Nerve block is injected right next to the nerve supplying sensation so knocks it out, and infiltration goes into the soft tissues and works on a shallower level.
