*update*

The cracked tooth is not the one that was hurting. I'm looking at a root canal on Monday on #18, then eventually a crown. A crown on #19, if it stays pain free, but it must be crowned asap so the root does not get compromised. If it hurts before I can crown it then I need an additional root canal before the crown. A huge huge filling is also needed in the back, on tooth #20. He said ideally it should be hollowed out and crowned as well, but as he put it, while grimacing: "that depends on your financial situation"
