text: I had a cracked tooth once, and I went through a filling first (will no relief), then a root canal (with no relief again), and finally I told my dentist to just pull the tooth (because I couldn't take the pain anymore).  If you haven't felt any better results by Monday go back again, or seek another dentist.  I was told that once you have a cracked tooth, there's basically nothing they can do for it.  Have it pulled--if it's in an unnoticeable area (mine was the very back tooth), before you go through all of the pain and expense I did.
