    Compared to other parts of your body, the tissue inside a tooth makes for a special case.

    When it becomes inflamed (like in response to advancing decay or other type of insult), its blood and lymphatic vessels that are needed to transport white blood cells and nutrients to it for defense and repair become restricted (compressed by the accompanying swelling that occurs within the tooth).
