Split molar after bridge prep

So.... I had some dental work two weeks ago. I was missing a molar in my back. I was so excited to finally get that taken care of.

We decided I was going to get the bridge, so they did the prepping for it. They shaved down the teeth next to it, and they said the bridge was like a 3 tooth crown. Well, on Friday, one of my back teeth (not the missing one) split in the back. It hurts to push on it, and I'm eating very carefully. I'm scared they're going to have to pull that one or what if I can't get the bridge now or what if I have to pay more money.

I've already paid $1200, and that's a lot of money from me. I'm afraid what if I am just out $1200, and now they can't even do the bridge because they have to remove the other tooth. I can't afford implants, which is why I got this bridge in the first place.

It's almost like I would have been better just leaving the hole in my mouth. SIGH
