Why do teeth have nerves attached to them if the only thing they do is get infected and hurt?

What is the evolutionary advantage of teeth having nerves? tooth enamel is the hardest substance in the body so why is the inner part of the tooth something that just drives you crazy when it's exposed?

Ever have a root canal or a dead or fake tooth? You actually do have feeling in your teeth which help you know how much pressure you are applying onto something or when to stop biting because there is a bone or rock in your food that is breaking them. You don't necessarily need the nerves but you use the feeling in your teeth more than you realize.
