A: A re-root canal. At the dentist check up last week, the xrays showed infection (or something) in a front tooth that I originally had root canal-ed in 1991. The doc said, "Well, they must not have got all the root back then, cause there's something still left... and we gotta get it out." This all started in 1987. I was 15. I got my braces off, and two week later I dove into shallow water and cracked several front teeth. No neck damage. I had my front two teeth completely removed in 1991 and anchors put in, and fake teeth installed. Then I had to have all of that redone in 2004. So... here we go again. I'm expecting them to find more stuff to have to deal with once they get into it. They always do. I haven't had any pain from this at all. Yet.
