what it means if your tooth dies
A dead tooth is a tooth that does not have a nerve inside it. The nerve has died. Normally teeth DO have a nerve inside them. It's what tells you if your coffee is hot or your ice cream is cold! I usually tell my patients that a tooth is a bit like a pencil. The nerve inside the tooth is like the pencil lead, running down the inside of the tooth. It's possible for the nerve to die and shrivel up.
