A big chunk of my tooth broke off

[Black Diamond Bay]

over the weekend. It's one of the back molars. It has a filling in it, and actually last summer a little chunk of the tooth broke off, but it didn't hurt at all. Then Sometime between Friday night and Saturday morning a larger chunk must have broke off and I guess I swallowed it because the whole back part of the tooth is missing now and it hurts a bit.

So I have an appointment to see the dentist tomorrow about the matter. My dad's telling me I'm probably getting a crown. How long does it take for them to actually install the thing in my mouth? None of this sounds very fun, but right now it's interfering with my ability to eat, and I so I figure I better go get the problem addressed sooner rather than later.
