Dentist never bothered to look at my other teeth?

So I broke a tooth in half about a year ago and they gave me options of what could be done. I said just pull it out, since it's not in front. So now fast forward a year later, I decide to finally get this thing pulled. Should have just went straight to an oral surgeon the previous dentist referred me to. Anyways, this latest dentist did a whole exam and tells me I have like $8k worth of stuff wrong with my mouth. I need a root canal on another tooth, the tooth that is broken needs to be pulled now where the first dentist said a root canal could be done, but the second dentist said there isn't ebough for them to attach a crown to and just needs to be pulled. I don't get it. The first dentist took xrays. Why didn't they mention the other cavities? Could have saved myself a root canal. Now I'm just going to have both my upper premolars pulled I guess, and the other cavities filled. Something doesn't line up here. Opinions? Yes, I should have gotten the broken tooth fixed by now, but I didn't know that's the only thing they looked at. I assumed everything else was fine since they took xrays and didn't mention anything else. What a bunch of bs. Now I need to see a 3rd dentist to make sure that 2nd one isn't ripping me off.
