ELI5: Why do my teeth hurt when my drink is too cold?
gpt
The nerves in your mouth become numbed by the cold like if you put an ice pack on a bruise, but since your teeth are more important than a bruise your body freaks out and thinks that something bad happened because it is no longer receiving a signal from your numbed teeth so it tells you that it hurts so you will figure out what is wrong and fix it.
